The PCM3 valve is available as two or three-way pressure compensator, developed as modular version with mounting surface according to the ISO 4401.
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 used together with proportional directional valves, in order to control the flow rate independently of pressure variations.
The selection of the pilot 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 socket hex adjustment screw or an adjustment knob.
The fixed adjustment compensator is available with setting (characteristic ∆p) of 4 and 8 bar.
Tech Specs: p max 350 bar - Q max 40 l/min
