Product Description
The sealing principle of a gate valve operates through the precise contact between the wedge-shaped gate's dual sealing surfaces and the corresponding sealing surfaces within the valve body. When the gate moves into the closed position, these matching surfaces create a tight mechanical seal that effectively prevents fluid leakage through compression and surface conformity.
This wedge-gate sealing mechanism delivers exceptional sealing performance with consistent reliability across varying pressure conditions. The stable contact between multiple sealing surfaces ensures long-term leak-tight operation while maintaining structural integrity under high-pressure applications, making it ideal for critical shut-off services.
