Features WM stable performance wedge structure hoist flexible Z-agency special seal to avoid leakage of large torque electric wedge gate valve Product Overview doing valve is a linear motion, which match with the Z-type multi-turn actuator with a switch type and Intelligent. This valve is the most common simple opening and closing the valve, which uses the shutter down to work to turn on and off the pipeline fluids. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other sectors. 1, the fluid resistance is small, the sealing surface by erosion and erosion of small media (gate turn high). 2, open the more powerful, good sealing performance, medium flow unrestricted, non rope flow, the pressure does not drop. 3, simple shape, good manufacturing processes, using a wide range. 4, the smaller the torque required for valve closing.
