Duplomatic PCM3 - Two and Three Way Pressure Compensator

Duplomatic Oleodinamica represents the real alternative in the hydraulics market. Duplomatic’s wide range of products and worldwide service network, grant its users a real competitive advantage.

The Duplomatic PCM3 valve is a two or three-way pressure compensator, developed as a modular version with mounting surface according to the ISO 4401 (CETOP RP121H). Its aim is to keep the pressure drop setting (characteristic ∆p) between the line P and alternatively the lines A and B, at a constant level. It is normally used together with proportional directional valves, in order to control the flow rate independently of the pressure variations.

The selection of the piloting pressure on the lines A and B is carried out automatically via a shuttle check valve built into the compensator. The setting of the variable adjustment compensator (characteristic ∆p) can be varied from 7 to 33 bar, via a countersunk hex adjustment screw or via an adjustment knob. The fixed adjustment compensator is available with setting (characteristic ∆p) of 4 and 8 bar.
