API 6D Gas Flat Gate Valve for Petroleum Natural Gas
 
Main Features:
1) The seat ring uses a floating design with an O-ring seal and pre-tightening force, allowing dual-sealing at both inlet and outlet. This structure reduces the opening and closing torque by half compared to standard valves, making it easier to operate.
 
2) When fully open, the valve has a smooth and linear flow path, resulting in minimal resistance and no pressure loss. It allows pipeline cleaning using a hairball.
 
3) The valve automatically releases high pressure from the internal cavity before closing, ensuring safety during operation.
 
4) The fully sealed design provides excellent protection, suitable for continuous 24-hour operations.
