Product catalog summary
Functional Description: The RPE3-04 directional control valves are composed of a cast iron housing, a control spool with centering springs, and operating solenoids. These valves are available in two configurations: three-position valves with two solenoids and two springs, and two-position valves with either one solenoid and a return spring or two solenoids with a detent assembly. Solenoids are DC powered, with AC options available through integrated rectifiers. Manual override is possible if the T-port pressure is below 363 PSI.
Specifications: The valves are phosphate and zinc coated, with installation dimensions conforming to DIN 24 340 / ISO 4401 / CETOP RP121-H standards. They support a maximum operating pressure of 320 bar (4600 PSI) and a flow rate of 30 L/min (8.0 GPM). The solenoids can be rotated 360° for flexible installation.
Ordering Code: The ordering code includes options for nominal size, number of valve positions, seal types, orifice sizes, manual override types, and electrical connector configurations. Solenoid voltage options range from 12 V DC to 230 V AC.
Technical Data: The valves operate with petroleum oils and phosphate ester fluids, within a fluid temperature range of -30 to +80°C. They support a maximum switching frequency of 15,000 cycles per hour and have a service life of 10 million cycles. The enclosure type is IP 65, and the valves can be mounted in any position.
Performance Characteristics: The p-Q characteristics detail the operating limits for maximum hydraulic power and pressure drop related to flow rate. Specific spool symbols are provided for different configurations.
Dimensions: Detailed dimensions are provided for valves with one or two solenoids, including mounting and electrical connector specifications.
Additional Information: The document includes details on solenoid coil types, electrical connectors, orifice options, spare parts, and preferred valve types. It also notes that the packaging is recyclable and that mounting screws must be ordered separately.

Directional Control Valves Solenoid Operated 4/3-, 4/2- way directional control valves with solenoid control Solenoids can be turned around their axis to any position Push button manual override Installation dimensions acording to DIN 24 340 / ISO 4401 / CETOP RP121-H Subplates see data sheet HA 0002 Functional Description The RPE3-04 directional control valves consist of cast WE3-04 iron housing (1), control spool (5) with two centering springs (4) and operating solenoids (2, 3). The three-position directional valves are fitted with two solenoids and two springs. Two-position directional valves have either one solenoid and one return spring or two solenoids and a detent assembly. The operating solenoids are DC solenoids supplied through connectors A, B (6, 7). For AC supply the solenoids are provided with a rectifiers which are integrated in the DIN connector socket as part of the solenoid. By loosening the nut (8), the solenoid can be turned around its axis up to 360°. In the case of solenoid malfunction or power failure, the spool of the valve can be repositioned by manual override (9), provided the pressure in the T-port does not exceed 363 PSI (25 bar). The valve housing (1) is phosphate coated and the solenoids (2, 3) are zinc coated.
