Two or three -way pressure compensator, with fixed or variable calibration, the PCK06 valve is a two -way or three -way pressure compensator, cartridge, available with a fixed or variable calibration, installed in blocks or panels. It keeps the pressure difference constant between the PSCER line P and the X piloting line. It is used in combination with the proportional management valves in order to create independent flow controls from the pressure variations. The variable calibration compensator can be calibrated between 7 and 33 bar by means of adjustment screws built -in or with adjustment knob. For the fixed calibration version, calibrations with ∆p characteristic of 4 and 8 bar are available.
