Abstract
A coating material dispensing device includes a port adapted to be coupled to a source of coating material, an actuator for controlling a flow of compressed gas through the dispensing device, and a valve coupled to the actuator to be controlled by the actuator. The valve includes a valve housing, a valve closure member, and a valve seat. The valve closure member is 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 is provided into the housing. The inlet port is oriented on a first side of the valve seat. The inlet port is adapted to be coupled to a source of the compressed gas. An outlet port is provided on the second side of the valve seat. The valve closure member includes 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.
