Bosch Rexroth 4WEH22E74 Hydraulic Solenoid Valve

Bosch Rexroth 4WEH22E74 is a size-22, four‑way electrohydraulic directional valve in the 4WEH family designed for pilot‑operated control of hydraulic flow in industrial circuits. It is a solenoid‑actuated valve with a 24 V DC coil and is configured for reliable actuation of hydraulic actuators, such as cylinders, in machine tools and automation lines. The valve uses a 3‑pole DIN EN 175301‑803 electrical connector (2 power + PE) and porting that follows ISO 4401‑08‑08‑0‑05, enabling standardized installation. Hydraulic fluids supported include HL, HLP, HLPD, HVLP, HVLPD, and HFC, making it suitable for mineral oil–based systems. In Rexroth literature, this family is described as pilot‑operated and appropriate for precise directional control of hydraulic circuits.
