Gate Valves 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.

Tchnical specification:
Before assembling, all parts should be clean, no oil or grease,remove all burrs and sharp edges.
Before connecting, body cap male thread should be coated with sealing glue
Handle turn or close freely.
After assembling, test by water at pressure no less than 0.6MPA. no leakage.
