The gate valve's opening and closing component is the gate plate, which moves perpendicular to the fluid direction. Gate valves can only be fully open or fully closed, not used for throttling or regulation. The gate plate has two sealing surfaces. In the commonly used pattern gate plate valves, the two sealing surfaces form a wedge shape, with the wedge angle varying with the valve parameters, typically 50°, and 2°52' when the medium temperature is not high.The gate of a wedge gate valve can be made as a single piece, known as a rigid gate plate; or it can be designed to undergo slight deformation for improved processability, compensating for deviations in the sealing surface angle during the manufacturing process. This type of gate is called an elastic gate plate. Stainless steel gate valves are categorized into 304 stainless steel, 316 stainless steel, and 321 stainless steel. The representation is: Z41H-16P.
