Pressure-Sealing Gate Valve is a type of gate valve that relies on medium pressure to achieve self-sealing. The "sealing" characteristic lies in that when the medium pressure acts on the disc, the disc will tightly fit the seat, achieving good sealing effect without requiring additional sealing mechanisms.
This design simplifies the valve structure, reduces maintenance costs, and improves reliability.
Pressure-sealing gate valves are widely used in petroleum, chemical, power generation, and water treatment industries for controlling the flow of various media.
