4WE6R73B6X/EG96N9K4/A12V

The 4WE6R73B6X/EG96N9K4/A12V valve is part of the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow to actuators in automated machinery. A porting pattern of ISO 4401-03-02-0-05 matches standard subplates to simplify installation. The pressure ports p, a, and b withstand up to 350 bar, while the tank port t is limited to 210 bar, letting the device operate safely in high-pressure circuits. A maximum flow of 80 l/min defines the throughput the spool can handle without excessive pressure drop. The solenoid requires a nominal voltage of 96 V DC, and a ±10 % voltage tolerance keeps performance stable despite supply variations. With a rated current of 0.33 A and a nominal power consumption of 30 W, coil heating stays moderate during service. A duty cycle of 100 % ED permits continuous energization, making the valve suitable for applications that demand long holding periods without rest intervals.

The DIN EN 175301-803 (K4) electrical connector standardizes the wiring interface so field technicians can use common cable sets. An IP65 ingress protection rating guards internal components against dust and low-pressure water jets, enabling outdoor or wash-down installation. A concealed manual override lets maintenance staff shift the spool mechanically while preventing unintended actuation during normal operation. FKM seal material resists mineral oils and higher temperatures, extending service life in demanding hydraulic fluids. The coil tolerates switch-off overvoltage up to 500 V, protecting the winding insulation from inductive spikes when power is removed. A switching-time increase code of A12 designates the response profile chosen for circuits that favor smoother actuation over ultra-fast movement, rounding out the electrical and mechanical features that tailor this valve to precise flow control tasks.
