OnC DiscValve 550

OnC DiscValve 550

Armature for a multitude of applications

The OnC DiscValve is a soft-sealing valve that blocks liquids and gases and performs simple control tasks. The modular design of the valve simplifies parts replacement.

OnC DiscValve valves with a centrally seated valve disc are maintenance free. The soft-sealing seat is replaceable and is available in EPDM, NBR or FKM materials, depending on flow applications. A version with a cemented collar is available for vacuum applications. An enclosure with PTFE lining is also available.
The materials GG25, GGG40 and stainless steel 1,4408 are available for the enclosure. Depending on the material specification chosen and the flow medium, the valve blocks differential pressures up to 16 bar. The valves can be fitted with pneumatic actuators, final position monitoring units or positioners.

OnC DiscValve valves can be used with a multitude of applications for blocking liquids and gases.
