Pressure Sealing Gate Valve

Pressure seal gate valve is mainly used to cut off or control the flow of fluid under high pressure and high temperature conditions. The gate of pressure seal gate valve is the main working part of pressure seal gate valve, and the fluid is cut off or controlled by controlling the opening and closing of the gate through the transmission device. The advantage of pressure-sealed gate valve is that its valve seat and gate are under the action of fluid pressure to produce better sealing effect, that is, the greater the pressure, the tighter the seal. In addition, the pressure sealed gate valve has high straightness of fluid passage and low fluid resistance, which can effectively reduce the energy consumption and cost of the system.
