Product features of q41f46 flange type fluorine lined ball valve
1. The inner wall of lined ball valve is smooth and the flow passage is unobstructed, which is the least resistance of all valves.
2. The switch is quick and convenient, and the opening and closing action can be completed by rotating the ball 90 degrees.
3. The lining material is lined on the inner wall of valve shell by special molding process, which can resist the corrosion of strong acid and alkali medium. The combination of lining spherical surface and PTFE valve seat has good sealing performance and zero leakage.
4. It can be equipped with pneumatic, electric, hydraulic and other driving devices to realize remote control and automatic operation
5. The ball and the valve stem are integrated to eliminate the rotation angle difference, eliminate the risk of the valve stem rushing out of the body due to the pressure change, and ensure the safety and reliability of use.
