Product features

The electric wafer type ultra-thin ball valve is especially suitable for the installation and use of short pipelines and special spaces. It has the characteristics of compact structure, short length, small volume, close distance between the valve seat and the end flange, less material retention, and superior sealing performance. Compared with ordinary ball valves, electric wafer ball valves are a new generation of ultra short flange pitch ball valves. The shape of the ball core channel is V-shaped and O-shaped, which can be widely used in petroleum, chemical industry, metallurgy, power stations, light industry and other fields to automatically adjust or cut off oil, water, gas and pulp or fibrous fluids.

Features of electric wafer ball valve:
 
The electric wafer type ball valve has the remarkable advantages of short structure length, light weight, convenient installation, material saving, etc. It is suitable for situations where the installation position is relatively short. It is easy to maintain, and the valve design is easy to disassemble. At one end of the valve, there is a screw bonnet, which controls the tightness of the valve seat and the ball core seal and the switch.
