Plast-O-Matic CKS Diaphragm Check Valves

Series CKS Check Valves are normally-closed in design. They feature a corrosion-resistant PFA encapsulated spring, which energizes a poppet seal that will neither stick nor chatter and is automatic in action. The valves are not dependent upon gravity or reverse flow and represent a significant improvement over ball check valves. They can be mounted in any position. Even in the absence of reverse flow or pressure, the poppet will automatically reposition itself to seal against the valve seat. The unique poppet will seal in the same location every time, producing a reliable and repetitive seal.
