Forged Gate Valves Flanged

Flanged Gate Valves are primarily designed for on-off services when a straight-line flow of fluid and minimum restriction is desired. The closure member of gate valves either stops or allows flow through the valve and acts somewhat like the opening or closing of a gate and is called, appropriately, the gate valve. The gate is also shown as a wedge, due to the shape is resembles. When the valve is open, the closure member is fully drawn up into the valve, leaving a complete opening for the flow stream. Therefore, there is little pressure drop or flow restriction through the valve. Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Gate valves are not suitable for throttling purposes.

These valves are widely used in Refineries and Petrochemical Industries, Fertilizer Plant, Thermal Power Plant and other process industries. With socket and screwed end connection, these valves are designed for handling very high pressures. Its rigid and sturdy design along with low pressure across the valve make it a very formidable model in the entire product line.
