The H-4WEH16E42-7X/6EG24N9K4 is a directional spool valve from Bosch Rexroth in the WEH Directional Spool Valves series. It directs hydraulic flow in automated machinery using electro-hydraulic actuation, so the main spool is shifted by pilot oil controlled through a 4WE 6E pilot valve. The unit employs a 4/3-way configuration to provide three distinct spool positions for pressure and tank paths. A pressure-centered design returns the spool to center when pilot pressure drops, and this function engages once the pilot line falls below the 16 bar minimum. Subplate mounting simplifies replacement in manifolds while the ISO 4401-07-07-0-05 porting pattern maintains interchangeability across equipment. The nominal size 16 flow paths suit medium-frame actuators. Solenoid coils rated at 24 V DC energize the pilot stage, and electrical connection uses a DIN EN 175301-803 K4 plug for quick installation and sealing.
Operating limits are matched to high-pressure circuits; ports P, A, and B tolerate 350 bar, allowing the valve to drive cylinders in power-dense systems. The pilot stage can be supplied with up to 250 bar, ensuring fast spool shifts under full load, while port Y for pilot drain is limited to 210 bar to protect the return gallery. Tank port T withstands 250 bar, so back-pressure in counterbalance networks will not impair function. With a maximum flow capacity of 300 l/min at nominal size 16, the valve accommodates rapid actuator speeds without excessive pressure drop. Clean operation relies on hydraulic fluid maintained at 20/18/15 according to ISO 4406; this cleanliness level prevents wear in the precision-ground spool lands and extends service life. Together these pressure, flow, and contamination limits define the valve’s operational envelope and help designers integrate it safely into closed-loop hydraulic automation systems.
