About Gate Valve
This valve has inside a gate that moves up-down perpendicular to the flow of the service. In the up position it will open and vise versa in the down position it will be closed. The flow is straight through, and does not lend itself for use as a metering valve.
The Gate valve is also available 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.
The gate valve is used mainly as an on /off valve. This Gate Valve is also called as a Bi Directional Gate Valve.
Mostly API 600/603 standard Gate valve contructions are bolted bonnet with rising spindle Pressure seal design bonnet design used for high pressure application from class 900 pressure rating.
Rising Stem
Outside Screw & Yoke (OS & Y) design keeps the stem threads outside the valve and is recommended where high temperatures, corrosives, and solids in the line might damage the stem threads inside the valve. When Gate Valve will open, the stem extends above the hand wheel indicates the position of the gate.
Valve Trim
A trim means internal working parts of valves. In Gate Valves the Stem (Spindle), Seat Ring, Back Seat Bush, Gland Bush is trim.
Integral Seat
These types’ seats are integral with body casting. Machined into the body casting.
Renewable Seat
Separate Seat Rings that screw into the valve body, which is called as Renewable Seats.
