3/8 Inch Hex Body, Umbrella Check Valve

CAD Model


Description: The CKVU series high flow check valve permits free flow in one direction and no flow (checked) in the opposite direction. This valve is specified in many applications because of its very low cracking pressure (typically less than 0.5 psig), its excellent repeatability, and leak-tight operation. This valve also provides significantly higher flow than the CKV series check valves.

Max Back Pressure Rating: 250psig

Approximate Weight: 8g in brass and 303 stainless.

Porting: 10-32 internal threaded inlet and outlet ports.


  • Larger diameter umbrella style checking element permits higher flows than our duckbill check valve designs.
  • Elastomeric umbrella checking element allows for cracking pressures around 0.5 psig.
Note: The CKVU is currently out of stock and unavailable for order ahead of a next-generation design release.
