API 6D Gas Flat Gate Valve for Petroleum Natural Gas

Gate Valves: API 6D Flat Gate Valve used for natural gas

 
Main Features:
1) The seat ring uses a floating seat ring structure with an O-seal ring and pre-tightening force, providing dual-sealing on both inlet and outlet sides. This design reduces the opening and closing moment by half compared to conventional valves, making it easier to operate.
 
2) When fully open, the valve's flow path is smooth and linear, resulting in minimal resistance and no pressure loss. It allows for easy pipeline cleaning using a hair ball.
 
3) Automatically removes high pressure from the internal cavity just before closing, ensuring safe operation.
 
4) A fully sealed structure ensures excellent protection, suitable for continuous 24-hour operation.
