Introduction to Z941 National Standard Electric Flange Gate Valve

1、 Application and characteristics of Z941 national standard electric flange gate valve

Electric flange gate valveIt is the most common type of on-off valve that uses the up and down movement of the gate to open (fully open) and close (fully close) the fluid medium in the pipeline.
1. The fluid resistance is low, and the sealing surface is less susceptible to erosion and erosion by the medium (due to the high opening height of the gate).
2. Strong opening, good sealing performance, unrestricted flow of medium, no turbulence, and no pressure drop.
3. Simple in shape, good in manufacturing process, and widely applicable.
