With the improvement of technologies of valve, valve areas continuously expanding, the corresponding valves standard is more and more indispensable. Valve industry has entered a period of innovation, product categories require not only new replace, internal management of enterprises also need to be based on industry standards for further reform.
Double Plate Check Valves are designed to automatically prevent backflow in systems where it is desirable to permit flow in one direction and prevent flow in the opposite direction. When the pump starts and the downstream flow creates the required pressure drop in the forward direction, the Dual Plates will automatically open. When the pump stops and the flow ceases, the torsion of the spring will automatically close the Dual Plates prior to flow reversal.
