Product Overview
The Rexroth H-3SEW6C3X/420PGEG24N9K4/SO615 (Material No. R902126869) is a direct-operated, solenoid-actuated directional seat valve designed for leak-free load holding and precise flow direction control in high-pressure industrial hydraulic systems. Featuring a poppet-type seat design within a 6-size (NG6 / CETOP 3) subplate interface, this valve provides zero-leakage sealing in the closed position, making it ideal for safety-related clamping, holding, and isolation circuits. The integrated 24 V DC wet-pin solenoid with N9 (DIN EN 175301-803, ISO 4400) connector and manual override enables reliable electrical actuation in automated machinery. The “420” pressure rating indicates a high-pressure variant capable of withstanding up to 420 bar in the P-port, while the SO615 designation denotes a specific seat/spool configuration for directional control. As a genuine Rexroth component, it delivers the precision, durability, and repeatability required for demanding industrial duty cycles.
