Abstract

See full text

A drain valve comprising a body, an inlet for fluid to enter the drain valve, an outlet for fluid to exit the drain valve, a piston member having a piston head and a piston shaft, a seat against which the piston head seats in a closed condition of the drain valve, and a rotatable member that is rotatable relative to the body. The rotatable member is rotatably retained with the piston shaft, such that rotation of the rotatable member in one direction causes the piston member to move in a first linear direction away from the inlet such that the valve head is unseated from the seat to open the drain valve and, in use, allow fluid to enter the drain valve via the inlet and discharge via the outlet. Rotation of the rotatable member in the opposite direction causes the piston member to move in a second linear direction toward the inlet to seat the valve head on the valve seat to close the drain valve and, in use, prevent fluid from entering the drain valve via the inlet.
