The Z4WE6E137-3X/EG96K4 solenoid-operated valve is produced by Bosch Rexroth as part of the Z4WE Solenoid Actuation Spool Valves series. Intended for hydraulic automation, it meters and redirects flow between subplate ports according to spool symbol E137 for predictable actuation logic. The ISO 4401-03-02-0-05 porting pattern lets the body bolt to standard NG6 manifolds, while a maximum operating pressure of 315 bar at ports P, A, and B supports high-pressure circuits. Flow capacity reaches 50 l/min, and the 1.7 mm integrated orifice provides damping to curb pressure shocks. Oil cleanliness must meet ISO 4406 20/18/15 to maintain spool precision, and NBR seals confine mineral-based fluids without leakage. The IP65 protection class prevents dust ingress and low-pressure jets from affecting the energized coil.
Electrical performance centers on a 96 V DC coil that draws a rated current of 0.33 A and consumes 30 W, enabling steady force on the spool. A DIN EN 175301-803 (K4) plug connector supplies this power and offers quick replacement in the field. Continuous operation is supported by a 100 % ED (S1) duty cycle, and the assembly can switch up to 15 000 cycles per hour for high-frequency control loops. Back-pressure tolerance is defined by a 210 bar limit at port T, preventing tank line overloading. A mean time to dangerous failure of 150 years underlines the reliability expected in safety-related circuits.
