Pneumatically operated 2/2 way angle seat valve with stainless steel actuator
The pneumatically operated angle seat valve with stainless steel actuators fulfils the demands of tough process environments. Unrivalled life time and sealing integrity is guaranteed by the trusted self-adjusting spindle sealing. The stainless steel actuator has been designed for tough applications. Laser welding ensures it is both cleanable and robust. With a ducted exhaust air port, the actuator can be operated isolated from the environment to guarantee an optimum life time and hygiene. High flow rates are attained with the optimised stainless steel angle seat body. As part of the Bürkert process valve range a large accessory program is available. All wetted parts comply with the EC Directive 1935/2004, variants with FDA conformity are available on request, also explosion proof variants are available.
