Proportional valve regulatory of piloted flow rate The RPC2 valves- They are used for adjusting the flow rate in hydraulic circuit branches and for the control of the speed of hydraulic actuators. They are available in three adjustment fields brought: two with progressive gain up to 72 l/min and one with differentiated earnings of 30 l/min. For the correct operation of the valve, a minimum piloting flow of 2 l/min and a minimum pressure of 20 bar must be ensured. The piloting can be internal to the valves, taking oil from the "E", or external, with 1/4 "BSP attachment on the pilot body. The drainage is always external and must be connected directly to the tank without counter -tropping using the Wall (or Ø35) or tube (1/4" BSP attack) available on the pilot body. The three-way version RPC2-70-T3 allows the adjustment of the flow rate towards users, sending its excess value unloading. You can adjust the maximum pressure in the circuit through a manual calibration valve that operates on the piloting of the compensator. The valves can be controlled with a controlled power supply in current or via an electronic card, to be ordered separately.
