PAR-15 (Patent No. 4,630,632) is a unique 3-way programmable air regulating valve that functions as a precision, high-flow, multi-purpose binary regulator. The response from the valve is virtually instantaneous and repeatable, thus reducing the need for feedback controls. Full flow exhaust permits instant reduction to any lower selected pressure or zero. High relief capacity quickly vents downstream overpressure. The output pressure will begin to change 20 milliseconds after a change in the electrical input of one or more of the solenoids.

The PAR-15 is available with two types of output pressure regulation:  increasing output and decreasing output. The increasing output pressure regulation type (normally closed (NC)) solenoid operators are used to divide the input pressure into 15 equal steps ranging from 0 PSIG (all solenoid operators de-energized) to full line pressure (all solenoid operators energized).  With the decreasing output pressure regulation type (normally open (NO)) solenoid operators are used to divide the input pressure into 15 equal steps, but starting with full line pressure (all solenoid operators de-energized) and ending with 0 PSIG (all solenoid operators energized). Signals from a controller, fed to the valves four solenoids, are controlled by on/off signals that selectively divide any input pressure into any one of fifteen equally spaced pressures, plus zero, based upon a binary input truth table.
