Abstract:
1. A coating material dispensing device including a port adapted to be coupled to a source of coating material, an actuator for controlling a flow of gas through the dispensing device, a valve coupled to the actuator to be controlled by the actuator, the valve including a valve housing, a valve closure member, a valve seat, the valve closure member movable in the housing under the control of the actuator between a closed position against the valve seat and an open position away from the valve seat, an inlet port into the housing, the inlet port oriented on a first side of the valve seat and adapted to be coupled to a source of the compressed gas, an outlet port on the second side of the valve seat, the valve closure member including a first surface which faces generally in a first direction of movement of the valve closure member away from the valve seat and a second surface which faces generally in a second direction of movement of the valve closure member toward the valve seat, and a skirt extending from an outer perimeter of the closure member past the inlet port when the valve is in the closed position for reducing exposure of the first surface to the source of compressed gas.
