Door Knocker

The gate valve consists of four parts: valve seat (body), valve plate, sealing ring, and hinge. It is used exclusively for circular and square outlets with unidirectional water flow. The structure is tight, the operation is reliable, and manual operation is not required. The opening and closing force comes from the water pressure of the source. When the water pressure inside the gate valve is greater than the pressure outside, it opens; conversely, it closes.
