Pilot-operated check valve
60 l/min, 320 bar | FT3 CP F.lli TOGNELLA


  • Operation:



Fluid flows freely on P and T lines; on service lines A and/or B with p.o. check, fluid flows from A → A1 (and/or B→B1) overcoming the force of spring acting on poppet and fluid is blocked from A1→A (and/or B1→B); when by switching the solenoid operated 4-way directional valve, pressure is made available at, for instance, port B fluid flows B→B1 and the pilot piston, Shifting from its central
position, forces poppet on service line A to open and permit flow A1→A.
