The Aircomp provides remote pneumatic control of the Denison line of relief valves including the R1E02 shown to the right. Not only does the Aircomp fit the full line of relief, sequence, and pressure reducing valves, it can also be used directly on some Denison pumps for adjusting pressure compensation. Used in conjunction with an air regulator, the rugged Aircomp provides infinite adjustability of the pressure relief setting. The Aircomp is easily installed in place of the manual adjusting screw assembly while retaining the standard Denison hardened cone.
