If you are researching the Burkert Type 2000 angle seat valve under part number 00001252, the first thing to understand is that the available technical evidence points to a very specific configuration. The attached research report identifies part 00001252 as a Type 2000, 2/2-way, control function A, normally closed, PTFE-seat, gunmetal-body valve with female G 1/2 threaded ports. It also explains that the most defensible OEM match is Article 1252, which appears to represent the same configuration class even though the exact string “00001252” was not found in an OEM PDF.
That matters because buyers rarely want a vague family-level summary. They want to know whether the Burkert Type 2000 angle seat valve they are considering is right for their pressure range, temperature range, media, pilot air setup, and installation conditions. In practice, that means looking beyond a product name and checking the real operating limits, construction materials, flow data, control function, and maintenance considerations before making a decision.
This guide rewrites the technical report into a practical blog format so it is easier to read and use. It covers what part 00001252 most likely is, what the Burkert Type 2000 angle seat valve is designed to do, how its key specifications affect real-world use, what installation and maintenance details matter most, and what to watch for if you are comparing it with nearby alternatives. Where exact part-specific data is unavailable, that limitation is stated clearly rather than hidden.
What Is the Burkert Type 2000 Angle Seat Valve 00001252?
The Burkert Type 2000 angle seat valve is a pneumatically operated process valve designed for reliable shut-off and media control across demanding industrial duties. In the case of part 00001252, the report consistently points to a 2/2-way angle seat valve with control function A, meaning it is normally closed by spring force and opens when pilot air is applied. For many users, that fail-safe closed behavior is one of the biggest reasons this valve style is chosen in the first place.
More specifically, the report ties part 00001252 to a configuration with a gunmetal body, PTFE seat seal, and female G 1/2 threaded process connections. That combination makes the Burkert Type 2000 angle seat valve appealing for users who need a compact threaded shut-off valve that can handle a meaningful pressure range while still supporting elevated media temperatures. The PTFE seat is especially important because it strongly influences sealing behavior, allowable temperature, and compatibility considerations.
The report also makes an important distinction: although the product is identified convincingly, not every line of data is proven as “00001252-only” from an OEM part-specific document. Instead, the strongest interpretation is that 00001252 maps to Article 1252, and therefore the valve should be understood through a combination of validated catalog attributes and matching Type 2000 family data. For a serious buyer, that is not a weakness. It is actually the most honest way to assess the Burkert Type 2000 angle seat valve without overstating certainty.
Burkert Type 2000 Angle Seat Valve Core Configuration and Why It Matters
A lot of technical confusion disappears once the Burkert Type 2000 angle seat valve is reduced to its core configuration. For part 00001252, the main attributes are straightforward: Type 2000 family, 2/2-way flow path, control function A, gunmetal body, PTFE seat, and female G 1/2 inner thread. Each of those details affects application fit.
The 2/2-way design means the Burkert Type 2000 angle seat valve is fundamentally an on/off shut-off valve rather than a multi-port directional valve. The control function A layout means the valve closes in its rest state by spring force, so pilot pressure is required to open it. In applications where loss of pilot air should force the valve shut, this is a practical and often preferred fail-safe arrangement.
The gunmetal body is another meaningful part of the configuration. It changes the allowable pressure envelope compared with some other body materials in the wider Type 2000 family, and it also has relevance for compatibility, regulatory attention, and use-case selection. The report notes that gunmetal variants are limited to 16 bar(g) even where other body materials in the family may support higher values. That means buyers cannot assume every Burkert Type 2000 angle seat valve performs identically just because the model family name is the same.
Then there is the PTFE seat, which is central to sealing and service conditions. PTFE is widely valued for temperature capability and chemical resistance, but it also has implications for leakage class, wear, and media suitability. When you combine PTFE with a G 1/2 threaded process connection, the result is a Burkert Type 2000 angle seat valve configuration that is compact, process-capable, and easy to integrate into threaded piping systems where a flanged body would be unnecessary.
Burkert Type 2000 Angle Seat Valve Pressure, Temperature, and Pilot Air Limits
One of the strongest reasons engineers look closely at a Burkert Type 2000 angle seat valve is its ability to work across demanding process conditions. According to the report, the most relevant operating figure for the 00001252 configuration class is 0 to 16 bar(g) for the gunmetal-body version. That is the pressure limit buyers should treat as the practical ceiling for this part class, even though the broader Type 2000 family includes variants with higher maximum values.
The temperature story is also important. The report notes that the closest validated catalog entry shows -10 to 185 C, while the matching gunmetal and PA actuator variant in the family datasheet shows -40 to +180 C for medium temperature. This is a good example of why the Burkert Type 2000 angle seat valve should be evaluated carefully by configuration and not by family name alone. Small differences in catalog presentation, material combination, or generation of datasheet can shift the published range slightly.
Pilot pressure matters just as much as media pressure. The family-level data in the report shows a pilot pressure range of 2 to 10 bar(g), with more specific limits by actuator size. For the likely G 1/2 / DN15 / actuator size 50 configuration, the minimum pilot pressure is about 4.1 bar(g) when paired with the PTFE seat and the relevant pressure class. In practical terms, the Burkert Type 2000 angle seat valve will not perform correctly if the plant air supply is inconsistent, undersized, or poorly regulated.
That is why valve selection should never end at “the body connection fits.” A Burkert Type 2000 angle seat valve may appear correct dimensionally but still disappoint in service if the available pilot pressure cannot reliably open the valve under expected line conditions. The interaction between pilot pressure, operating pressure, actuator size, and seat design is part of what makes this valve technically robust when sized properly and frustrating when selected casually.
Burkert Type 2000 Angle Seat Valve Flow Performance: Kv, Cv, and What the Numbers Mean
For many buyers, the most useful performance data on a Burkert Type 2000 angle seat valve is not the catalog photo or the body material. It is the flow coefficient. The report identifies the most relevant DN15 / G 1/2 data for the PTFE-seated threaded configuration and highlights a representative value of Kv 5.0 m3/h and Cv 5.78 for one common setup using actuator size 50 (D).
In simple terms, that means the Burkert Type 2000 angle seat valve offers solid flow capacity for its size class. The report also includes comparable values by actuator diameter for DN15. For example, actuator size 40 is shown at Kv 4.7, while size 63 reaches Kv 5.4. Even so, the report reminds readers that the gunmetal-body version remains limited to 16 bar(g), so flow data should never be isolated from pressure-rating data when judging fitness for service.
Another useful detail from the report is the estimated pressure-flow relationship derived from the Kv value. At roughly 1 bar differential pressure, the flow estimate is about 5 m3/h, which aligns with the published Kv definition for water at 20 C. For users trying to understand whether the Burkert Type 2000 angle seat valve is enough for a compact liquid service line, this is the kind of number that helps bridge the gap between datasheet language and real engineering judgment.
The report also mentions an older legacy value of about Kv 4.2 m3/h for a closely matching threaded-port version. That should not be dismissed as a contradiction. It more likely reflects an earlier build version, older flow path, or different sizing convention. In other words, the Burkert Type 2000 angle seat valve has a documented performance range across generations, and that is exactly why current selection should be based on the most relevant configuration data available.
Burkert Type 2000 Angle Seat Valve Materials of Construction and Media Compatibility
Materials define whether a Burkert Type 2000 angle seat valve is merely installable or genuinely suitable. The report provides a meaningful breakdown of the construction stack for the gunmetal-body, PA-actuator class aligned with 00001252. It includes a gunmetal valve body, PTFE seat seal, stainless steel spindle and pin, NBR piston seal, PTFE V-ring packing, graphite body seal, stainless spring, and brass swivel plate.
This combination tells you several things immediately. First, the Burkert Type 2000 angle seat valve is built for more than light-duty clean air service. The materials support broader industrial use, including elevated temperatures and repeated pneumatic actuation. Second, the packing and seat arrangement suggest that sealing performance and wear resistance were important design priorities. Third, because the valve includes mixed metals and polymer components, media compatibility still has to be checked carefully rather than assumed.
The report states that the broader Type 2000 technical data covers media such as steam, water, neutral gases, alcohols, oils, fuels, hydraulic fluids, salt solutions, alkalis, organic solvents, oxygen, and fuel gases, subject to material selection and approval code. That breadth is one reason the Burkert Type 2000 angle seat valve is widely respected in process applications. Still, broad family compatibility does not remove the need to verify the exact media against the exact seal and body combination.
One especially important caution in the report concerns gunmetal bodies. A REACH-related note indicates that some alloy housings may contain lead as an alloy component. That does not automatically disqualify the Burkert Type 2000 angle seat valve, but it does mean that drinking water, food-related, and highly regulated applications deserve an extra level of diligence. Smart buyers do not just ask, “Will it fit?” They ask, “Is this exact material set appropriate for my service, my standards, and my regulatory environment?”
Burkert Type 2000 Angle Seat Valve Flow Direction, Control Function, and Installation Practice
The Burkert Type 2000 angle seat valve is not just about ratings on paper. It also depends on correct orientation and correct flow-direction choices. The report explains three control functions across the family, but the relevant one for part 00001252 is Control Function A, where the valve is closed by spring force in the rest position. When pilot air is applied, the valve opens. That sounds simple, but the surrounding installation rules matter a great deal.
One of the clearest operational warnings in the report involves flow direction above seat versus below seat. For the Burkert Type 2000 angle seat valve, the report states that flow direction above seat must not be used for liquid media because of the risk of pressure surge or water hammer. Above-seat flow is positioned as suitable for gas or steam contexts, while below-seat flow is the correct approach for liquids. That single point can prevent serious performance and reliability problems.
The report also notes that installation is allowed “as required,” but the preferred arrangement is with the actuator upright. That is a practical recommendation because the Burkert Type 2000 angle seat valve is easier to service, inspect, and operate consistently when installed in the posture the manufacturer prefers. In addition, the valve is identified with IP67 protection, which adds confidence for real industrial environments where splash protection and enclosure performance matter.
Another installation advantage is adjustability. The report explains that pilot air ports and actuator positioning can be aligned, and in certain configurations the actuator can be rotated through 360 degrees. That means the Burkert Type 2000 angle seat valve can be integrated more flexibly into crowded layouts where pilot tubing, access, and service space are constrained. Good valve selection is not just about media and pressure. It is also about how gracefully the valve fits into the actual piping system and maintenance workflow.
Burkert Type 2000 Angle Seat Valve Maintenance, Wear Points, and Common Failure Modes
A properly selected Burkert Type 2000 angle seat valve is designed for durability, but it is not maintenance-free in the absolute sense. The report says the actuator itself is considered maintenance-free when used as intended, yet certain parts remain natural wear items, especially seal elements and the swivel plate. That is a realistic and useful distinction for anyone planning lifecycle cost, downtime risk, or spare-parts stocking.
The report also highlights the manufacturer’s service position: use original accessories and original spare parts. For the Burkert Type 2000 angle seat valve, the named replacement sets include an actuator seal set and a valve set containing the swivel plate, pin, and graphite seal. This matters because many valve problems do not begin as catastrophic failures. They begin as gradual wear, subtle leakage, poorer repeatability, or inconsistent shutoff under load.
Torque and assembly also matter more than many buyers expect. For the seat size 15 class, the report notes an actuator-to-body tightening value of 45 +/- 3 Nm. That may seem like a minor detail, but improper torque can compromise the sealing geometry of the Burkert Type 2000 angle seat valve, increase wear, or create avoidable leakage paths. In process environments, small assembly mistakes often become expensive reliability problems later.
The report lays out several common failure modes. Seat leakage can result from low control pressure, excess operating pressure, or wear in the swivel plate or seat seal. Pressure-surge events can occur if above-seat flow is used with liquids. Packing gland discharge points to packing wear. Sluggish actuation may come from contaminated pilot air or restricted pilot plumbing. These are all practical reminders that the Burkert Type 2000 angle seat valve performs best when the surrounding air supply, installation logic, and maintenance discipline are just as sound as the valve itself.
Burkert Type 2000 Angle Seat Valve Pneumatic Interface and Automation Add-Ons
The Burkert Type 2000 angle seat valve is, at its core, a pneumatic valve. That means its base operation depends on pilot air, not direct electrical actuation. The report makes this distinction clearly and notes that electrical requirements only become relevant when the valve is paired with pilot solenoid valves, position feedback devices, or control heads.
For control function A, the report explains the basic behavior: applying pilot pressure opens the Burkert Type 2000 angle seat valve, while the internal spring returns it to the closed state when pilot pressure is removed. In a typical control scheme, plant air is regulated through an FRL arrangement, then routed through a 3/2 pilot solenoid or control unit before reaching the actuator pilot port. Exhaust management also matters, especially when consistent response and clean pneumatic performance are required.
The report further identifies a set of compatible automation add-ons associated with the Type 2000 platform. These include control head Type 8691, pneumatic control unit with feedback Type 8690, electrical position feedback Type 1062, pilot solenoid valves Type 6012 and 6014, and valve blocks Type 8640 and 8644. This modularity is one reason the Burkert Type 2000 angle seat valve remains attractive across varied process-control environments.
For buyers, that flexibility has a practical meaning. You are not limited to a bare shut-off component. The Burkert Type 2000 angle seat valve can serve as the foundation of a more instrumented and automated assembly if the process requires visibility, remote actuation, or integration with a broader control architecture. That makes it easier to scale from simple pneumatic service to more sophisticated process control without abandoning the same valve family.
Burkert Type 2000 Angle Seat Valve Compliance, Approvals, and Application Confidence
Approvals do not make a valve good, but they do help define where a Burkert Type 2000 angle seat valve can be specified with confidence. The report states that the 2026 conformity framework references the Pressure Equipment Directive 2014/68/EU and the Machinery Directive 2006/42/EC. It also notes a broader EU Declaration of Conformity that additionally references ATEX 2014/34/EU, Gas Appliances Regulation EU/2016/426, and other framework details tied to option codes.
That wording is important because it reminds buyers that not every Burkert Type 2000 angle seat valve carries every approval in the same way. Some declarations are tied to specific variable codes, such as PX51 for explosion-protection-related applicability. In other words, the family may support certain compliance paths, but the actual valve ordered must carry the correct coded configuration if those approvals are needed in the field.
The report also points to other optional suitability frameworks inside the Type 2000 ecosystem, including drinking water, food-contact, oxygen, DNV, fuel gas, and TA Luft-related options depending on variant codes. That means the Burkert Type 2000 angle seat valve is not simply a generic shut-off device. It is a configurable process platform that can align with specialized environments when the right build is selected.
RoHS is handled carefully in the report as well. It notes that a bare pneumatic valve may not fall into RoHS scope in the same way electrical and electronic products do, while accessories such as control heads, position feedback modules, or pilot solenoids may. For anyone building a documented procurement package, that nuance is valuable. The Burkert Type 2000 angle seat valve should be evaluated as a system, not only as a body and actuator.
Burkert Type 2000 Angle Seat Valve Alternatives, Availability, and Buying Considerations
Even if part 00001252 is the target, smart procurement rarely stops at a single number. The report notes that if 00001252 / Article 1252 is obsolete, restricted, or simply hard to source, there are practical alternatives within the same family. These include other G 1/2 gunmetal PTFE normally closed configurations listed in the Type 2000 catalog, as well as versions using stainless body or different actuator materials for changed environmental needs.
This matters because the Burkert Type 2000 angle seat valve is not a one-size-fits-all product. It is a family with multiple material and pressure combinations. If your process needs the same functional behavior but not necessarily the same exact legacy ordering number, newer article numbers may provide a cleaner procurement path while preserving the same design logic. The report specifically notes example article numbers that appear as close equivalents in the catalog.
The report also describes pricing variation across channels. OEM direct listings for nearby equivalents appear in the mid-hundreds of USD, a reseller listing for the exact 00001252 appears higher, and a UK distributor lists a configurable family version in GBP with a stated lead time. The takeaway is simple: the Burkert Type 2000 angle seat valve may be available through multiple routes, but pricing alone should not drive the decision.
A cheaper listing is not automatically the better choice if it does not clearly match the required control function, seat material, body material, thread type, or approval path. When comparing suppliers for a Burkert Type 2000 angle seat valve, the right question is not only “How much?” It is “Does this listing match the exact operating logic and build characteristics my application requires?” That is the difference between buying a part and solving a process problem.
