Keep your air, gas flow or water flow moving in the right direction: get an industrial check valve as a backflow prevention device. A heavy-duty non return valve can be joined with other valves, backflow preventers, and ball valves to ensure proper operation of your system. Choose the type of flow control valves that meet your needs. Our selection includes: one way, quarter turn, and two port; hydraulic, inline, and magnetic; pneumatic check valves, foot valves, double check valves, and wafer check valves; stainless steel, plastic, or pvc/cpvc; 2 inch or ½ inch. Check valves are used in water pumps, sump pumps, refrigeration, appliances and general plumbing applications. If you frequently work with different types of valves, keep in mind that we also supply relief valves, solenoid valves, gate & globe valves and many others.
