Beswick Engineering’s Stainless Steel Check Valves

Beswick’s stainless steel and brass check valves are ideal for instruments requiring a low cracking pressure (less than 0.5 psid). The valve also has excellent repeatability, and leak-tight operation. 
These check valves are designed with an elastomeric duckbill and can withstand up to 250 psid in the checked direction. Barbed connections and various elastomers are available. The check valve permits free flow in one direction and no (checked) flow in the opposite direction.
