Product features：
1.Advanced rocket-spraying process ensures that sealing is realiable under all temperatures — pressures. With hydrogen used as fuel, this process has been applied to the sealing faces of the ball and the valve seats;
2. Flow resistance is small；
3.Piston seat, fire protection-antistatic structure design；
4.No limitation on the flowing direction of medium；
5. When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;
6.Spring loaded packing can be chosen;
