Duplomatic’s wide range of products and worldwide service network, grant its users a real competitive advantage.
The PCM8 valve is a two or three-way pressure compensator, developed as a modular version with mounting surface according to ISO 4401 (CETOP RP 121H).
Its function is to keep the pressure drop setting (characteristic ∆p) between the line P and alternatively the lines A and B at a constant level.
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.
They are available with fixed adjustment (characteristic ∆p) of 4 and 8 bar.
The load sensing port can also be used as pressure gauge port or as remote pressure control.
