The 4WRTE16W6-200L-4X/6EG24EK31/A5M valve belongs to the 4WRTE Directional Control Valves series manufactured by Bosch Rexroth and directs hydraulic flow in automated machinery. Valve size NG16 specifies the mounting envelope for manifold blocks, while the ISO 4401-07-07-0-05 porting pattern matches standard subplates. The spool symbol W6 defines the internal flow paths selected during actuation, and a linear flow characteristic delivers proportional change between spool stroke and flow rate. Spool position monitoring is included so the control system can verify commanded positions. A 6E pilot control valve shifts the main spool with precision, and interface type A5 groups the electrical supply, signal lines, and feedback in one connector.
The electromagnetic stage accepts a nominal 24 V DC supply and permits up to 35 V DC, drawing a maximum of 1.6 A; a 4 A time-lag external fuse protects the circuit. A 100 % duty cycle rating allows continuous energizing without coil overheating. Pilot oil can be supplied internally and returned externally, giving flexibility in circuit design. The IP65 protection class seals the housing against dust and low-pressure water jets. Maximum operating pressure is 350 bar, supporting high-pressure hydraulic circuits. The assembly weighs 11.2 kg, which guides bracket and manifold selection during installation.
