With a wide range of valve body and disc materials available, the plastic pneumatic butterfly valve covers a huge range of applications in most industries, although the most common application is with a wide variety of water applications from swimming pools, through water treatment, to drinking water.
For water applications a PVC air actuated butterfly valve fitted with the AVP pneumatic actuator offers a commercially competitive solution with sizes from 2" to 12". Generally PVC pneumatic butterfly valves are wafer pattern although lugged and tapped versions can be supplied on request. The Cepex Extreme butterfly has a fully lugged body but uses through bolts as standard, making it a wafer butterfly valve, unless the threaded inserts are fitted.
The high quality EU manufacturer Cepex specialise in the manufacture of plastic valves in various materials, incorporating the different material discs in a common GRPP body. This popular version of the Cepex Extreme butterfly valve has a PVC disc with an EPDM liner.
AVP Pneumatic actuators are sized with 6 bar air available at the AVP actuator, should 6 bar not be available contact All Valves Online to check the pneumatic actuator sizing.
