The gate plate of the wedge gate valve can be made into an integral body, called a rigid gate plate, or it can be made into a gate plate that can produce a small amount of deformation to improve its manufacturability and make up for the deviation generated in the processing of the sealing surface angle. This kind of gate plate is called an elastic gate plate.
