Ball valves are also widely used in the gasification field of coal chemical plants, because they contain special media such as solid particles and sulfur under working conditions, and have good sealing, but they will leak during our use.

The pneumatic regulating ball valve can realize proportional adjustment. It can be used together with two position five-way solenoid valve and control box to realize on-off control. The valve core of V-shaped ball valve is designed with V-shaped notch with special shape, with accurate closure physical properties and control function, and is suitable for various control occasions.

Greater reliability (safety) of pneumatic cut-off valve: the valve body is an integral structure, which is firm and durable, the operation is not affected by pipeline pressure, and the leakage of valve body can be avoided. The electric explosion-proof butterfly valve is composed of V-shaped valve body, ZSQ pneumatic actuator and other accessories. It is a control valve with right angle rotation structure

V-type ball valve does not need to be repaired for a long time and has a long service life. It provides you with a valve with real high efficiency to control process conditions. There may be unreasonable design of the valve stem packing ball, unreasonable factors of material selection caused by the concentricity tolerance of the ball valve stem and the valve stem switching valve. When the wear of stem and packaging increases, the packing mating surface of the valve stem is seriously worn, so as to reduce the stem diameter, and then dry along the leakage axis of the medium of the flow path valve.
