Tips: How does a flanged gate valve work?
A flanged gate valve is a type of linear motion valve used to control the flow of fluids in pipelines. It consists of a flat gate with a seating surface that moves perpendicular to the direction of flow. The gate is attached to a stem, which is operated by a wheel-like handwheel or actuator. In the closed position, the gate seals against the valve seat, preventing fluid passage. To open the valve, the handwheel is turned, lifting the gate and allowing fluid to flow through the open space. Flanged connections on the valve body facilitate easy installation and removal. This design is ideal for applications where a straight-line flow with minimal pressure drop is required. Flanged gate valves are commonly used in industries such as oil and gas, water treatment, and manufacturing.
