The electric wafer ball valve is composed of DSR electric actuator and ultra-thin ball valve. Compared with ordinary electric ball valve, the electric ultra-thin ball valve (electric wafer ball valve) has compact structure, small volume, light weight, and the distance between the valve seat and the end flange Nearly, there is less material retention and superior sealing performance. Generally, electric wafer ball valves are suitable for occasions with relatively short installation positions, and are widely used in automatic control in chemical, petroleum, pharmaceutical, light industry and other industries. The V-channel sphere structure is matched with an electronic electric actuator to realize flow adjustment.
The pneumatic wafer ball valve is composed of a single (double) acting piston pneumatic actuator and an ultra-thin ball valve. Pneumatic ball valve can be equipped with valve positioner input control signal (4-20mADC or 1-5VDC) air source to control the operation. It can also be equipped with stroke limit switch, solenoid valve, pressure reducing valve and 0.4～0.7MPa air source to realize switch operation, and send out two pairs of passive contact signals to indicate the switch of the valve. Pneumatic ultra-thin ball valve (pneumatic wafer ball valve) has rectangular, V-shaped and O-shaped ball core channels. This series of products has the characteristics of compact structure, small size, light weight and convenient installation. Therefore, the pneumatic ultra-thin ball valve (pneumatic wafer ball valve) is widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to automatically adjust or cut off oil, water, gas and pulp or fibrous fluid.
