Application
The Z41 National Standard Manual Flange Gate Valve is one of the most common on-off valves that utilizes the up and down work of the gate to connect (open) and shut off (fully close) the fluid medium in the pipe. These gate valves are widely used as conditioning and shut-off devices in pipelines such as tap water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, marine, metallurgy, and energy systems.
