Product Description

The double flange plunger valve, also known as a sluice valve or gate valve, is a mechanical device used to control the flow of fluids in pipelines. Its design consists of a wedge-shaped gate or plunger that moves perpendicular to the flow direction to open or close the valve. The double flange configuration refers to the flanged ends of the valve body, facilitating easy installation and connection to pipeline systems.

Key Components and Operation

The primary components of a double flange plunger valve include the valve body, gate or plunger, stem, actuator mechanism (such as a handwheel or motor), and flanges. When the valve is open, the gate or plunger is raised to allow fluid to pass through. Conversely, when the valve is closed, the gate or plunger descends to obstruct the flow, creating a tight seal against the valve seat.
