The new Beswick 3/8 inch hexagonal body check valve (CKV38) provides a low cracking pressure (less than 0.5 psid) along with greater flow capacity than our smaller 5/16 hexagonal body check valves. It is capable of providing a maximum flow rate equivalent to a 5/64 inch (2mm) diameter orifice. The increased flow capability, low cracking pressure, excellent repeatability and leak tight operation can be used to advantage in a wide range of applications. The inlet and outlet ports can be specified with 1/8 inch (3.2 mm) ID barbs, ¼-28 UNF internal threads, or ¼-28 UNF external threads. This check valve can be ordered in either 303 or 316 stainless steel. Seal material options include Silicone, EPDM, and Viton®.
