Manual ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, not easy to wear the seal, and small opening and closing torque. This reduces the size of the fitted actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict shut-off of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict cut-off.
Manual ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Its specifications are as follows:
