Design Considerations

The 426 Check Valves incorporate a Stainless Ball that seals on a quad ring

Gray PVC with 1 psi stainless spring and ball is the standard configuration

Most PVC and White Filled Polypropylene configurations are available as NSF Standard 42 Certified

Nylon, PVDF (Kynar®) and Glass Filled Polypropylene are available for chemical resistance applications

MakroBlend is an NSF Standard 51 Approved Material

Hastelloy is a superior chemically resistant spring material

Teflon® balls are standard with Hastelloy springs for chemical resistance applications
