The electric drive function is strong, including switch type, intelligent type, explosion-proof type, and regulating type
The electric ball valve is a fixed ball valve and a single seat sealing ball valve. Its regulating performance is the best among ball valves. The flow characteristics are equal percentage, and the adjustable ratio is:. There is a shearing effect between its shaped notch and the metal valve seat, which is especially suitable for media containing fibers, tiny solid particles, slurry and other media.
Type electric ball valve has the same rotational action, but the difference is that the cock body is a sphere with a circular through hole or channel passing through its axis. Electric ball valves are mainly used to cut off, distribute and change the flow direction of media in pipelines. They only require a rotational operation and a small rotational torque to close tightly.
Electric ball valves are most suitable for use as switches and cut-off valves, but recent developments have designed ball valves to be used for throttling and controlling flow, such as electric ball valves.
