Dual Plate Check Valve
The Dual Plate Check Valve from Hitech Valves is engineered for compact, lightweight, and efficient non-return operation. Its dual-spring-loaded plates ensure quick closure, minimizing water hammer and protecting downstream equipment in high-flow systems. The wafer-style body design makes installation easy between standard flanges.
This valve is widely used in water transmission lines, HVAC systems, oil & gas pipelines, chemical plants, power plants, desalination units, and general process industries.
