ABSTRACT:
A drain valve for replacement of drain plugs or drain valves to facilitate the quick drainage of fluid from an equipment. The drain valve has a tubular housing assembly having a threaded section to be threaded into a threaded drain hole and a hexagonal nut section for assisting in mounting or removing the tubular housing assembly to threaded into or from the drain hole. A valve stem assembly has a valve stem which extends through the tubular housing assembly and has an actuator which an operator can push to open the drain valve. A compression spring disposed between the valve stem assembly and the tubular housing assembly provides a force on the actuator to force the drain valve into a closed position. Inlets in the valve stem permit fluid to flow through a drainage bore in the valve stem when the drain valve is in the open position.
