Description
Bürkert 2/2-way pneumatic angle seat valve (type 2000) with DN 25 welded end ports. The valve has a stainless steel housing with FKM sealing and an orifice size of 25 mm. The control function of the valve is normally closed (NC), which means the valve opens when air is applied. Suitable for a media temperatures from -10 to 130°C (14 to 266°F) at a pressure of -0.9 to 16 bar (-13 to 224 psi). The valve is suitable for vacuum down to -0.9 bar (-13 psi) and has a Kv-value of 19 m3/h (Cv-value of 22.0 gpm). The stainless steel housing is durable, suitable for corrosive media and harsh environments. FKM has very good overall chemical resistance. It offers good mechanical properties, resistance to compression set, suitable for high temperatures (not for hot water/steam). Good resistance to oils and solvents such as aliphatic, aromatic and halocarbons, acids, animal and vegetable oils. Not resistant to methanol. Consult our chemical resistance chart to verify compatibility of housing and seals with the medium. This valve is ATEX and IECEx certified, zones 21/1 and 22/2.
Pros:
- ATEX and IECEx certified, zones 21/1 and 22/2
- Y-shape design allow for higher flow capacity and Kv value compared to vertical globe valves
- Easily mount a compact Burkert 8697 position feedback and control unit on the actuator (not included)
- Suitable for vacuum down to -0.9 bar (-13 psi)
Cons:
- Flow above seat can cause water hammer when used with liquids. Use flow below seat versions for liquids
- Type 2000 doesn't have a control cone, so it is not as suited to regulate flow rate as Burkert type 2702 or 2712
Series:
The Bürkert type 2000 2/2-way angle seat valve is a pneumatically actuated on/off valve. The CLASSIC pneumatically operated piston actuator is available in PA, or PPS for higher ambient temperatures. The valve body has been optimized for excellent flow properties and is equipped with a self-adjusting packing gland for added tightness and long-term reliability. These valves are suitable for high viscosity media of up to 600 mm2/s. This valve can be controlled through the use of a pilot valve or through central automation with a valve island. The valve can be fitted with accessories like electrical position feedback, manual override or stroke limitation.
