It is Bi Directional valve, is ideally used for isolation [On – Off] purpose, not advisable for flow control, flow throttling.

Operating Principles

A Stem [shaft] which moves perpendicular to the axis of flow of the working medium, there will be one gate or wedge in gate valve and it will control the fluid flow. Shape of gate or wedge of gate valve will be a type of flat circular plate or rectangular plate. Sometimes, gate or wedge is also termed as disc of gate valve.

Gate Valve handle wheel when rotated in clockwise direction, steam and gate will move in downward direction across the fluid flow line and gate will be tightly located between the two seats. Hence there will not be any leakage of fluid through the valve once valve is closed completely. When handle wheel will be rotated in anti-clockwise direction, steam and gate will move in upward direction across the fluid flow line and valve will be opened from closed position and will permit the flow of fluid through the gate valve. Once gate valve is completely opened, it will permit no resistance or very little resistance to the flow of fluid.


JD Controls Gate Valves are Outside Screw, Rising Stem, Bolted Bonnet Construction, threads are away from the line fluid and easy to lubricate.

The body bonnet joint for all class of Gate Valve is in CircularRound/Rectangular Shape. In Gate Valve from 150# Rating body & bonnet joint have male-female type joint with a gasket. The Gate valve is also available in different types of Disc-Gate such as Double Disc Gate, Solid Gate, Flexible Gate, Parallel Slide Gate, Conduit Gate etc. to suit industrial various applications.
