Function, section
The proportional pressure reducing valve type FTDRE 2 K… reducesthe pressure in port A in proportion to the solenoid current. It operatesvirtually independently from the pressure in port P.
The valve is suitable for the control of directional valves and hydrauliccylinders, particularly those in the mobile and automotive technologysectors.
The hydraulic pressure in port A acts on a spool (1) against thesolenoid force.
With the proportional solenoid (2) de-energised a return spring (3)at the spool (1) switches to the connection from A to T.
The valve can be supplied with the nominal voltages of 12 V and24 V. Operation is only permissible with a suitable amplifier (seetechnical data).
Attention!For mains operation an isolating transformer with separated windingsis required.
For optimum operation the solenoid must be filled with the pressurefluid (also see technical data "Installation").
Technical data (for applications outside these parameters please consult us!)
GeneralWeight kg approx. 0.16
Installation optional, preferably with the electrical connection hangingdownwards, (when the valve is horizontally mounted or if theelectrical connection is pointing upwards then a minimum backpressure pT has to be created to ensure that the valve stays full of oil)
Ambient temperature range °C – 30 to + 120
Solenoid surface protection coating to DIN 50 961-Fe/Zn 10C
Salt spray test to DIN 50 021 h 144
HydraulicSet pressure (pA) see tolerance range on page 3
Input pressure (pP) bar ≤ 100
Back pressure (pressure pT at port T) bar zero pressure (valve pressure tight up to 30 bar)attention: back pressure pT increases the set pressure pA, even with current I = 0
Flow details valid for BP Dexron II and + 80 °C– Flow (Δp = 7 bar) L/min ≥ 2 (max. permitted 7.5)– Max. leakage flow at port T at
pP = 100 bar and control current I = 0 cm3/min ≤ 80– Max. control flow at pP = 100 bar,
qV A = 0 and control current I = Imax cm3/min ≤ 350
Stepped response with control current alteration ton max. 25 ms(for test set-up see page 3) toff max. 20 ms
Pressure fluid mineral oils to DIN 51 524, ATF Dexron II, Fiat Tutela Multi F
Pressure fluid temperature range °C – 30 to + 80
Degree of contamination maximum permissible degree of contamination of the pressure fluidis to NAS 1638 class 9. We, therefore, recommended afilter with a minimum retention rate of ß10 ≥ 75.

Function, section
The 3/2-way directional valve type FTWE 4 KC controls the start andstop of a flow.
With the solenoid (1) de-energised the control spool (2) is held in itsinitial position by the return spring (3).
The solenoid force acts on the control spool (2) and pushes it out ofits normal position. The flow position from P to A is thereby opened.
The valve is particularly suitable for use in the mobile hydraulic andautomotive technology branches.
