The 3WH6A5X/B12/5 valve belongs to the WEH Directional Spool Valves series manufactured by Bosch Rexroth and directs flow in hydraulic automation circuits. It matches ISO 4401-03-02-0-05 and the Cetop D03 size, so its mounting face fits standard subplates. The NFPA T3.5.1 R2-2002 D03 interface and the DIN 24340 Form A porting pattern maintain dimensional compatibility across regional standards. Subplate mounting lets technicians remove the unit without disturbing fixed pipework. A nominal size of 6 provides compact passages, three ports connect pressure, tank, and actuator lines, and two switching positions change flow paths as defined by spool symbol A. Hydraulic actuation moves the internal spool.
The design carries up to 60 l/min while tolerating operating pressures to 315 bar for medium-pressure equipment. It accepts HL, HLP, HLPD, HVLP, HVLPD, or HFC fluids, so mineral-oil or water-glycol media can be used. A throttle insert with a 1.2 mm orifice, identified as B12, moderates pilot flow to smooth spool shifts. NBR seals contain the chosen fluid and resist degradation. The assembly weighs 1.26 kg, which simplifies manual handling during installation or service.
