5" Sleeve type drain valve in stock
Sleeve type drain valve is used to drain the volume fluid and release pressure when string testing finished. The ports in the sleeve of drain valve will be sealed with two sets of O rings before running in well, and the sliding sleeve and rotating nut are locked by two screws in order to keep the sliding sleeve tighten in course of downhole operation, attach drain collar after testing finished, rotate the rotating nut to make the sliding sleeve moves up until when the ports in the sleeve are aligned with the ports in the body of the tool, the fluid may be drained.
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.
Features and Benefits
• Allows pressure trapped between two closed valves to be relieved in a controlled manner
• Used to recover large volume fluid samples
