Electric wedge gate valve

Short Description:

The electric wedge gate valve is a kind of valve that moves in a straight line. It is matched with Z-type multi rotary actuator and has switch type and intelligent type. This valve is easy to operate, is one of the most common on-off valve, it uses the up and down work of the ram to connect and close the fluid medium in the pipeline. It is widely used in electric power, metallurgy, petroleum, chemical industry, papermaking, sewage treatment and other industries.
