Q361f floating worm gear all welded ball valve

Short Description:

Q41f46 flange type fluorine lined ball valve uses fluorine plastic as the lining of the ball valve, and is equipped with a new type of ball structure with rod. In addition, its unique elastic lip type sealing seat structure makes it have the advantages of ordinary ball valve. It can have high sealing performance and low operating torque in large pressure difference and large temperature range. It can be used as switch or adjustment. It is suitable for conveying liquid and gas (including steam) in various industrial pipelines. It can work well in various acid, alkali, salt and other corrosive media.

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.
