Product Name: Diaphragm Non-Return and Vacuum relief valves
Product Description
In PVC/Polypropylene or PVDF with diaphragm in Buna-N, Ethylene Propylene or FPM
The PLAST-O-MATIC "CKM" diaphragm check valves have only five parts, and only one which moves-the diaphragm. This provides both design simplicity and maximum operating dependability.
The diaphragm, a normally closed seal, will neither stick nor chatter. Even when the absence of inlet flow or pressure, the diaphragm will automatically reposition itself against the valve seat. This is achieved with or without the presence of reverse flow. The unique and patented diaphragm seal will seal in the identical location every time producing a more reliable and prolonged seal.
Because of its normally closed design the PLAST-O-MATIC "CKM" check valves can be installed in any position. Concern over the valve seat closing due to gravity (as with ball check designs) is of no consequence since "CKM" valves seal in any position.
The VB Vacuum Relief Valve available in PVC and PP feature the same sensitive diaphragm design as the Non-Return Valves allowing them to respond to a minimum of vacuum approximately 2"Hg (6.8kpa).
