Dual Plate Valve

The Dual Plate Check Valve is widely usable Non-Return Valve which is comparatively light in weight and stronger and also is small in size if compared with conventional Swing Check Valve. The Dual Plate Check Valve is uniquely designed by us and has also solved the problems which were faced with Swing Check Valve and Lift Check Valve. This specially designed Dual plate check valve utilizes two spring loaded plates attached on a central hinge pin. When the flow is reduced then plates are closed by torsion spring action and do not require reverse flow. There are two major advantages of No water hammer and Non-slam all together. All these feature of Dual Plate Check Valve make it the most unique and efficient design.
