Beswick’s miniature SS & brass check valves

Beswick Engineering Co., Inc.’s miniature stainless steel and brass check valves are ideal for instruments requiring a low cracking pressure (less than 0.5 PSID). The low cracking pressure permits free flow in one direction and no (checked) flow in the opposite direction. 

In addition to the low cracking pressure, the valve also has excellent repeatability and leak-tight operation. The 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.
