Abstract: Apparatus and a method for dispensing coating material through multiple dispensing devices. The apparatus includes a first pressure sensor which senses the pressure of a stream at a common point in a flow circuit and a number of second pressure sensors. Each of the second pressure sensors senses flow through a respective channel in the flow circuit. The apparatus further includes a controller for controlling the flows of the streams in the respective channels based upon the combined inputs of the first pressure sensor and second pressure sensors.

Abstract: A valve including a valve body, the valve body providing an inlet and an outlet, a valve seat between the inlet and the outlet, a valve member, the valve member and valve seat being relatively movable to control flow through the valve, the valve member engaging the valve seat to prevent flow through the valve and disengaging from the valve seat to permit flow through the valve.
