Our CHP series UHP fluoropolymer O-ring-free poppet check valves are designed to maximize flow while reducing pressure drop, eliminate no-flow areas, and provide excellent leak integrity during thermal cycling.

The O-ring-free design of the poppet ensures clean operation, and its contoured shape reduces turbulence and minimizes pressure drop
A shell seal with a tongue-and-groove design provides excellent leak integrity during thermal cycling and high-pressure applications
A spring composed of noncontaminating PFA material allows valve installation in any orientation. A positive stop prevents the spring from compressing to a solid height, allowing flow to sweep around spring coils to reduce entrapment.
In medium body sizes, the retainer is designed to maximize flow and reduce pressure drop. In small body sizes, the retainer’s open-cage design ensures poppet alignment and eliminates no-flow areas.

These valves can be installed in any orientation and are available with fine thread flare and Nippon Pillar^® Super 300 end connections.
