Argo-Hytos RPE3-062R21/20500E1 Hydraulic Solenoid Directional Valve

The Argo-Hytos RPE3-062R21 series is a direct-acting, solenoid-operated directional control valve with subplate mounting interface conforming to ISO 4401-03 (CETOP 3 / NG06 / NFPA D03). The valve features a 4-way, 2-position spool (type R21) with spring-centered neutral position connecting port P to A and port B to T. Maximum flow rating is 80 L/min (21 GPM). Maximum operating pressure at ports P, A, and B is 350 bar (5100 PSI); maximum tank pressure at port T is 210 bar (3000 PSI). The valve body is manufactured from high-strength cast iron with NBR seals as standard, suitable for mineral hydraulic oils within a temperature range of -30°C to +80°C. The specific variant RPE3-062R21/20500E1 is equipped with a 205V AC solenoid coil utilizing a DIN 43650 Form A (ISO 4400) connector. This valve series serves as a direct interchange for OEM hydraulic systems across multiple equipment platforms. Documented OEM cross-references include Liebherr part number 511432714 (for RPE3-062R11/02400R1/M), Sany part number 60035534 (for RPE3-062R21/020400E1-A on DTU95C asphalt pavers), and Rexroth part number 484-0788 (for RPE3-062R11). It is widely applied as a replacement component in hydraulic circuits of excavators, wheel loaders, agricultural tractors, and combine harvesters utilizing Argo-Hytos NG06 directional valves.
