GATE VALVES

What is a Gate Valve?

The gate valve derives its name from the presence of a closure component known as a gate, which can stop fluid flow through the pipe.

Within the gate valve’s body, there is a vertical disc that moves up and down perpendicular to the pipe’s flow direction. This movement either opens or closes the valve, employing the wedge-lock effect of the disc to block the flow.

Gate valves are ideal for regulating flow by enabling full opening or complete closure. Turning the handle counterclockwise raises the disc, allowing the flow to pass through the valve. Conversely, rotating the handle clockwise lowers the disc, restricting the flow.

Types of Gate Valve

– Wedge Type.
– Parallel Expanding Type.
– Parallel Slab Type.
– Parallel Slide Type.
– Knife Edge Type (design standard MSS-SP-81)
