Elastic ball ball valve


The ball valve is elastic. Ball and seat ring are made of metallic materials, sealing pressure than the large, rely on the pressure of the media itself has reached less than sealing requirements, must be an external force is applied. This valve is suitable for high temperature and high pressure medium.
Elastic sphere is an elastic slot open at the lower end of the inner wall of the sphere, and flexible. When the closed channel, the sphere rose stem wedge-shaped head compression to seal the open seat. First release the wedge-shaped head before rotating sphere, the sphere is restored with the original prototype, the small gap between the ball and seat, can reduce the sealing surface of the friction and operating torque.pilot valves
The ball valve can be divided into straight-through its channel position, tee and right angle. Tee and right-angle ball valve for the distribution of media and change the flow of the medium.shut off solenoid valve
