Q. What is the use of sluice valve?

Answer

Using only a wedge-shaped plate as the gate, a gate valve, also commonly called as simply sluice control valve, controls the flow of fluid in or out of the pipeline. Whenever the gate is fully opened, the disc of the aforementioned gate valve is completely severed from the flow. This provides flow resistance that is essentially nonexistent. As a result, the fluid flows through the gate valve with only a small amount of pressure loss. A sluice gate valve is the type of valve most frequently used in production plants to handle slurries.While in use, these valves are either entirely open or completely closed. Sluice gate valves cannot be used for precise throttling, hence they cannot be used. High pressure could make friction a problem. It gets harder to control the valve as the gate is pushed up against its own guide rail by that the pressure of the medium. In order to lower the pressure when the gated valve is opened, large gate valves frequently have a bypass that is managed by a smaller valve.
