Abstract
A pinch bar for a pinch valve is comprised of a coil spring coupled to one end of an actuating rod. An opposite end of the rod is formed with, or is coupled to a device or surface, which applies a pinch force. The actuating rod slides through a fixed-in-place rod actuator. The rod actuator, spring and actuating rod thus provide a mechanism that applies a closing force inwardly, into or directed toward a cabinet attached to which is a valve body for the pinch bar and against which the pinch bar could exert a tube-closing force.
