ABSTRACT:
A valve for a pressure feed paint cup. An adapter is attached to a lid for the cup. A check valve assembly is secured to a threaded end of the adapter which extends below the lid and a vent valve is secured to a threaded end of the adapter which extends above the lid. An air line is attached to the vent valve to supply pressurized air to the paint cup. The check valve has a spherical valve ball which engages a conical valve seat near the diameter of the ball to increase the seating force without increasing the valve opening force. The valve seat and the valve ball are formed from low friction materials. A valve stem is manually moved to first open a vent valve which vents air pressure from the air line and then to move the valve ball from its conical seat.
