Check Valve

Swagelok® Ultrahigh-Purity Polymer Check Valves (CHP Series)

Swagelok CHP series UHP fluoropolymer check valves provide low cracking and reseal pressures, and their wetted components meet SEMI Standard F57-0301 for ultrahigh-purity system components.

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.
