Z941W/Z941H/Z941Y electric stainless steel wedge flange gate valve is matched with Z-type multi turn actuator, available in switch type and intelligent type. A gate valve with flange connection, rising stem wedge type rigid single gate, valve seat sealing surface material of 2Cr13 stainless steel or hard alloy (STL), nominal pressure of PN16, valve body material of austenitic stainless steel, and the function of cutting and connecting pipeline medium. This electric wedge gate valve is the most common opening and closing valve with simple operation. The electric wedge gate valve uses the up and down operation of the gate plate to connect and close the fluid medium in the pipeline. Electric wedge gate valves are widely used in sectors such as power, metallurgy, petroleum, chemical, paper making and sewage treatment.
Application scope:
Widely used in sectors such as electricity, metallurgy, petroleum, chemical industry, paper making and sewage treatment.
Product advantages:
- The fluid resistance is small, and the sealing surface is less susceptible to erosion and erosion by the medium.
- Powerful opening, good sealing performance, unrestricted flow direction of the medium, no flow convergence, and no pressure reduction.
- Simple in shape, with good manufacturing craftsmanship and a wide range of applications.
- The required torque for closing the valve is small.
Product Disadvantages:
- The structural size is large, and the installation space is limited.
- The opening height reaches, but the opening and closing time is long.
- Sealing surface lifting switch, easy to scratch.
