CVIS Series - Modular Check Valves

CVIS Series - Modular Check Valves

CVIS spring loaded (spring assist) check valves use a modular design that is highly customizable. Spring loading provides positive shutoff. Free floating no spring versions are highly sensitive to the slightest change in pressure or flow. No spring designs also allow maximum flow volumes.

  • Glass-filled polypropylene housings
  • Red, blue or natural colored housings
  • Free floating no spring option available
  • Natural polypropylene cartridges and poppets
  • Spring loaded cracking pressures from 0.1 to 10 psi
