Floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet. Features: *Reliable s
The pneumatic ball valve is a a ball valve with pneumatic actuator . The actuating speed of the pneumatic actuator is relatively fast, the fastest switch speed is 0.05 seconds / times, so it is usually called the pneumatic fast cutting off the ball valve.
The electric ball valve is an important executive in the industrial automation control system. An electric ball valve is a valve that revolves around the axis of the stem according to this kind of movement of the valve disc. The change in the seat opening
The duplex stainless steel ball valve adopts the top entry structure, reduces the quantity of connection bolt of the valve body, enhance the reliability of the valve under the condition of high pressure and large caliber, and overcomes the influence of th
The trunnion ball valve is equipped with a movable seat ring which can generate displacement under the pressure of medium. In case that any medium pressure exists, the pressure will press the valve seat seal ring onto the ball tightly, guaranteeing the se
