Application

     The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its processability and make up for the deviation of the sealing surface angle during the machining process. The board is called a resilient shutter. When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the ram is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valves are forced to seal, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface. The gate of the gate valve moves linearly with the valve stem, which is called the lift gate valve, also called the open gate valve.

 Feature 

1. High height, long opening and closing time. The opening and closing stroke of the shutter is large, and the drop is performed by the screw.
2. The water hammer phenomenon is not easy to produce. The reason is that the shutdown time is long.
3. The medium can flow in any direction on both sides, which is easy to install. The gate valve channels are symmetrical on both sides.
