Directional Control Valves Solenoid Operated Size D 06 (03) ·350 bar (5076 PSI) · 80 L/min(21 GPM) Size D 06 (03) • pmax 320 bar (4641PSI) according to CSA 4/3-, 4/2- way directional control valves Solenoids can be turned around their axis to any position 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 HU 0002 Functional Description WE3 The RPE3 directional control valves consist of housing (1), a control spool (5) with two centering springs (4) and cylindrical operating solenoids (2, 3). The three-position directional control valves are fitted with two solenoids and two springs. Two-position directional control valves have either one solenoid and one return spring or two solenoids and a detent assembly. The operating solenoids are DC solenoids. For AC supply the solenoids are provided with a rectifiers which are integrated in the DIN connector socket as part of the solenoid. The connectors (6, 7) can be turned by 90°. By loosening the nut (8), the solenoids can be turned or replaced without interfering with any seals of the valve. In the case of solenoid malfunction or power failure, the spool of the valve can be shifted by manual override (9), provided the pressure in T-port does not exceed 25 bar. The valve housing (1) is phosphate coated and the solenoids (2, 3) are zinc coated.

Spool Speed Control Orifice Type Description Important: This directional valve provides control spool soft shifting by means of orifice situated in the solenoid armature.To ensure the proper function of the valve, perfect air bleeding of the solenoid is required (by us of bleeding plug (1). The plugs are accessible after removing the rubber boot (2) from the solenoid retaining nut (3). Switching times Switching time, on and off The switching times shown are valid for viscosity n = 32 mm /s (156 SUS) and nominal voltage. They are dependent upon working pressure and flow rate of the...
