4/3 directional valve
The valve type 4WRPE is a direct operated directional control valve with electric position feedback and integrated electronics (OBE).
Set-up
The valve basically consists of:
Valve housing (1) Control spool (2) with compression springs (3.1 and 3.2) Control solenoid with position transducer (4) (optional with electronics protection membrane (8)) Stroke solenoid (7) Integrated control electronics (OBE) (5) with analog interface (6) (optional with damping plate (9))
Function
The integrated electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the relevant solenoid will be activated. Due to the changed magnetic force, the control spool (2) is adjusted against the corresponding spring. Stroke/control spool cross-section is controlled proportionally to the command value. In case of a command value presetting of 0 V, the electronics adjust the control spool (2) to central position.
Error detection
In the following cases of error, the electronics will de-energize the control solenoids:
Falling below the minimum supply voltage ≤ 15 V (restarting ≥ 17.5 V). Design “F1”: falling below the minimum current command value of 2 mA (comprises the cable break of the command value line (current loop)The control spool (2) is kept in the mechanical central position by the compression springs (3.1 and 3.2) (does - with symbol V - not correspond to the hydraulic central position).
Damping plate "D"
The damping plate (9) reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz).
Notice:
Use of the damping plate is not recommended for applications with mainly low-frequency excitation <300 Hz.
Electronics protection membrane "-967"
To prevent condensate formation in the housing of the integrated electronics (OBE), an electronics protection membrane (8) can be used.
Recommended for use outside industry-standard conditions with high ambient air humidity and significant cyclic temperature changes (e.g. outdoors).
4/2 directional valve
The valve type 4WRPE is a direct operated directional control valve with electric position feedback and integrated electronics (OBE).
Set-up
The valve basically consists of:
Valve housing (1) Control spool (2) with compression springs (3) Control solenoid with position transducer (4) (optional with electronics protection membrane (8)) Integrated control electronics (OBE) (5) with analog interface (6) (optional with damping plate (9))
Function
The integrated electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the control solenoid will be activated. Due to the changed magnetic force, the control spool (2) is adjusted against the control spring. Stroke/control spool cross-section is controlled proportionally to the command value. With a positive command value presetting, the valve opens from P to B or A to T. Negative command values lead to no change in the control spool position.
Error detection
In the following cases of error, the electronics will de-energize the control solenoid:
Falling below the minimum supply voltage ≤ 15 V (restarting ≥ 17.5 V). Design “F1”: falling below the minimum current command value of 2 mA (comprises the cable break of the command value line (current loop).
Damping plate "D"
The damping plate (9) reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz).
Notice:

Command value:
Positive command value (0 ... 10 V or 12 ... 20 mA) at D and reference potential at E cause flow from P → A and B → T. Negative command value (0 ... -10 V or 12 ... 4 mA) at D and reference potential at E cause flow from P → B and A → T. With valves with solenoid on side a (symbol EA), a positive command value (0 ... 10 V or 4 ... 20 mA) at D and reference potential at E result in flow from P → B and A → T.
Connection cable (Recommendation):
Up to 20 m cable length type LiYCY 7 x 0.75 mm2 Up to 40 m cable length type LiYCY 7 x 1.0 mm2 EMC-compliant installation: Apply screening to both line ends Use metal mating connector (see "Accessories") Alternatively up to 30 m cable length admissible (not with version with damping plate) Apply screening on supply side Plastic mating connector (see "Accessories") can be used
