Check valve provides bubble-tight seal with no wetted metal parts

July 16, 2004
Self-sealing thermoplastic check valves for corrosive and ultrapure liquids are designed to safeguard process systems and maintain a positive closure even in the absence of reverse pressure. Offered in 1-1/2'''', 2'''' and 3'''' pipe sizes, the design uses a spring encapsulated with Teflon PFA to protect liquids from contamination.
