Product details
Introduction to Z973H-6 Electric Knife Gate Valve
Z973H-6 electricKnife gate valveIt is a type of valve that performs linear motion and is compatible with Z-type multi turn actuators, with switch type and intelligent type. This valve is easy to operate and is one of the most common types of opening and closing valves. It uses the up and down movement of the gate to connect and disconnect the fluid medium in the pipeline. Widely used in sectors such as power, metallurgy, petroleum, chemical, papermaking, and wastewater treatment.
Characteristics of Z973H-6 Electric Knife Gate Valve
1. Low fluid resistance, less erosion and scouring of the sealing surface by the medium (high gate opening)
2. Strong opening, good sealing performance, unrestricted flow of medium, no blockage, and no pressure drop.
3. Simple form, good manufacturing process, and wide range of applications.
4. The torque required to close the valve is relatively small.
