Check valves, also known as clack valves or one-way valves, are an inexpensive yet effective solution to controlling back flow in high and low pressure fluid systems. Available in a wide range of sizes and cracking pressures, our mechanical check valves can handle up to 6,000 psi and temperatures up to 600°F.
We maintain a large inventory of instrument check valves, including welded check valves, compact check valves, ball check valves, high pressure check valves, and adjustable check valves. End connection options include male / female NPT, Hy-Lok tube fittings, and metal gasket & O-ring face seals. Hy-Lok offers stainless steel check valves brass check valves, and alloy 400 check valves.
