Directional Control Valves Solenoid Operated Size 10 · pmax up to 350 bar · Qmax up to 140 L/min 4/3, 4/2 way directional control valves Cylindrical DC solenoids with removable coils. Electrical connectors can be rotated in three positions 90° apart Four-land spool - reduced functional dependence on fluid viscosity Push button manual override Installation dimensions to DIN 24 340 / ISO 4401 / CETOP RP121-H Subplates see data sheet HA 0002 Functional Description The RPE4-10 directional control valves consist of WE4-10 housing (1), control spool (5), centering springs (4) and operating solenoids (2, 3). The three-position directional control valves are fitted with two solenoids and two springs. The two position directional control valves have one solenoid and one return spring. The operating solenoids are DC solenoids and are supplied through connectors (6, 7) without rectifiers. For AC supply the solenoids are provided with rectifiers, which are integrated directly into the connectors (6, 7) or inside the coil. By loosening the retaining nut (8), the solenoid can be turned on its axis and locked in three positions 90° apart. Provided that the pressure in T-port does not exceed (25 bar), the spool of the valve can be shifted by manual override (9). The basic surface treatment of the valve housing (1) is phosphate coated, the operating solenoids (2, 3) are zinc coated.

Operating limits for maximum hydraulic power transferred by the directional valve. For respective spool type - see functional symbols. The power curves hold true for symmetrical valve flows (e.g. flows in directions P-A and B-T are identical). In case of an asymmetric flow, the power curves can lie substantially lower. In such cases we highly recommend to consult the respective power curve with the valve manufacture. Pressure drop Dp related to flow rate.
