Product Description

Specifications

As a professional high quality Taian Dual Plate Wafer Check Valve manufacturer,we will offer you the best after-sale service.When the medium flows in the specified direction, the valve opens under the thrust of the medium. When the medium flows in the opposite direction, the sealing surfaces of the valve disc and the valve seat close under the action of the self-weight of the valve disc and the reverse force of the medium, thereby preventing the backflow of the medium. The Dual Plate Wafer Check Valve design of this valve folds inward when flowing in the forward direction, effectively reducing the water hammer effect
