Check Valve Manufacturer in USA – SVR Global

SVR Global is a specialized Check Valve Manufacturer in USA, offering a wide portfolio of valves engineered to prevent reverse flow and protect pumps, compressors, and pipelines across industries. Our range includes swing, dual plate, lift, ball, and axial-flow designs, ensuring reliability in critical applications from water supply to LNG terminals.

Function & Working

Check valves are non-return valves that operate automatically without external actuation. The disc or plate opens under forward flow and closes immediately upon reverse flow, preventing backflow, water hammer, and equipment damage. Depending on the design—swing, piston, or axial-flow—our valves can handle clean fluids, slurries, gases, or cryogenic service.
