Hy-Lok Check & Relief Valves
As a leading supplier of premium fluid control products throughout the United States, SWPC Fluid Solutions is pleased to offer an extensive line of check and relief valves manufactured by Hy-Lok.
Hy-Lok check valves offer a reliable way to control backflow in high and low-pressure fluid systems. We offer our check valves in your choice of stainless steel, brass, alloy 400, and other materials with end connection options that include male/female NPT, tube fitting, metal gasket, and O-ring face seals.
Capable of handling pressures up to 10,000 psi at temperatures up to 600°F, we carry a full inventory of configurations to meet your applications.
- Our 700 series valves feature tight shut-off capabilities thanks to an integrated O-ring.
- With the 700H series, an O-ring poppet provides a replaceable high integrity seal.
- We also carry the RV series relief valves, featuring spring adjustable capability over the entire cracking pressure range.
- Our CVA adjustable line features a one-piece body construction for a wide range of cracking pressures.
All Hy-Lok relief valves feature a compact body for tight space installations, external cracking pressure adjustments, and a lock wire design to maintain relief settings. Like all other Hy-Lok valves, every check and relief valve is tested before it leaves the factory.
