32 Function, section The proportional pressure reducing valve type FTDRE K reduces the pressure in port in proportion to the solenoid current. It operates virtually independently from the pressure in port P. The valve is suitable for the control of directional valves and hydraulic cylinders, particularly those in the mobile and automotive technology sectors. The hydraulic pressure in port acts on a spool () against the solenoid force. With the proportional solenoid () de-energised a return spring () at the spool () switches to the connection from to T. The valve can be supplied with the nominal voltages of V and 4 V. Operation is only permissible with a suitable amplifier (see technical data).! ttention!

With the solenoid () de-energised the control spool () is held in its initial position by the return spring (). The solenoid force acts on the control spool () and pushes it out of its normal position. The flow position from P to is thereby opened.
