4WE6D73-6X/EG96N9K4/A12V

The 4WE6D73-6X/EG96N9K4/A12V valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs pressurized fluid to selected ports in hydraulic automation systems. The solenoid assembly is designed for a duty cycle of 100%, enabling uninterrupted actuation during extended machine cycles. A nominal voltage of 96 V DC integrates the coil with mid-range direct-current supplies, while a voltage tolerance of ±10% protects switching performance against minor line deviations. The coil draws a rated current of 0.33 A and consumes 30 W, aligning power demand with common control cabinets. Electrical connection is achieved through a DIN EN 175301-803 plug coded K4, simplifying field wiring and maintenance. An IP65 enclosure rating seals the housing against dust and low-pressure water jets, supporting installation in industrial environments. With two solenoids installed, the unit weighs 1.95 kg, keeping manifold or sub-plate mounting manageable for a single technician.

Hydraulic capacity is defined by a maximum flow of 80 l/min, permitting medium-flow circuits to operate without excessive pressure drop. Working ports A, B, and P withstand up to 350 bar, so the valve accommodates high-pressure pumps and actuators. Back-pressure at port T may reach 210 bar, allowing return lines to carry elevated residual pressure. A switching frequency of 4.2 cycles per second supports rapid directional changes in servo-type operations, while a switch-off overvoltage limit of 500 V safeguards the coil insulation during transient suppression. The mounting interface follows ISO 4401-03-02-0-05, and the NFPA code T3.5.1 D03 ensures interchangeability with standard sub-plates. Functional safety is enhanced by a mean time to dangerous failure of 300 years, giving long service life in continuous-duty machinery. These characteristics combine to provide precise flow control under demanding pressure, speed, and reliability requirements.
