Introduction of the Drain valve

The drain valve is used to drain the volume fluid and release pressure when string testing finished, including Sleeve Type Drain valve and Full Bore Drain valve.

The drain valve consists of a ported body, sliding sleeve, and rotating nut, which controls the position of the sliding sleeve. The sleeve either covers or exposes the ports in the body of the valve. The drain valve is suitable for sour service at all temperatures. A drain collar and associated components are required when relieving pressure.
