          General of gate valve

          Gate Valve are widely used in fluid-handing systems for flow control. Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The gate is usually wedge shaped. When the valve is wide open, the gate is fully drawn up into the valve, leaving an opening for flow through the valve the same size as the pipe in which the valve is installed. Therefore, there is little pressure drop or flow restriction through the valve. Gate valve have two types, rising-stem type and non-rising stem type.

          Forged steel flange gate valve Series:Gate Valve

          Forged Steel Valve are used in Oil Refining and other industrial applications where forged steel material is required. Higher pressures and temperatures are involved and the line size is generally under 2-1/2". Other factors could also favor the selection of forged steel, such as system requirements for socket-weld piping and compatibility of media.
