Soft Seal Gate Valve

Soft seal gate valve (elastic seat seal gate valve) is a key improved valve that uses non-metallic elastic materials (such as rubber) as the overall sealing pair on the basis of traditional gate valves. The gate is usually wedge-shaped, with rubber covering the exterior as a whole; The sealing surface of the valve body is machined to match the sealing surface of the gate plate. When the valve is closed, the gate descends and the rubber sealing surface tightly adheres to the valve body sealing surface under pressure, forming an elastic seal. This design gives it a significant advantage over traditional metal sealed gate valves, with excellent zero leakage sealing performance; Small closing torque, easy to operate; Rubber can absorb vibrations and compensate for certain deviations; And it has strong adaptability to fluids and is not easily blocked. However, its application is also limited by the characteristics of rubber materials and is not suitable for working conditions such as high temperature, high pressure, sharp particles, or highly corrosive media. The soft seal gate valve produced by Kaiweixi has become the mainstream shut-off valve in urban water supply networks, building water supply systems, and general fluid transportation fields due to its excellent sealing and economy, especially suitable for clean water media with strict sealing requirements.
