Dixon Sanitary HSC Spring Check Valves are a full 316L stainless steel check valve meeting 3A sanitary requirements. Dixon's new check valves feature a single piece upper body spider design that is machined from solid bar. These valves are designed to open when the pressure below the valve seat surpasses the cracking pressure of the spring, which will vary by the size of the valve (see chart below). FKM or EPDM seals available. Repair kits available to replace worn gaskets and O-rings.
