Abstract: A valve and position control system integrable with a clamp having at least one clamp arm moveable between a clamped position and a released position in response to movement of an actuator between first and second end limits of travel controlled by differential fluid pressure in first and second chambers located on opposite sides of the actuator. The system allows selective setting of at least one of the clamped position and the released position at an actuator position between the first and second end limits of travel of the actuator. The system selectively controls the speed of actuator movement as the actuator moves between the first and second end limits of travel. Preferably, the system also selectively controls the speed of actuator movement as the actuator approaches at least one of the first and second end limits of travel to provide a soft touch clamp action. The system selectively adjusts pressurized fluid within the first and second chambers independent of one another.

Abstract: Pressure flow regulator for use in pneumatic pressure control devices for maintaining a constant predetermined output pressure from a given constant or variable input pressure. The regulator includes a main housing, an inlet port, an outlet port, an air adjustment regulator and an insert assembly forming air passages when installed in the main housing. The insert is formed such that when inserted in a bore machined into a blank, the insert and the bore mate to form chambers and passages needed for pressure regulation of the pneumatic medium, in this case air.
