4WRVE16X200M-2X/G24ETK0/B5M-812

The 4WRVE16X200M-2X/G24ETK0/B5M-812 valve belongs to the 4WRVE Solenoid Directional Control Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It is built in size NG16, so it fits manifolds designed for that flow section. The mounting pattern follows ISO 4401-07-07-0-05, allowing direct installation on standardized subplates without additional adapters. A nominal flow of 200 l/min at a 10 bar differential lets the main stage meter large volumes while maintaining set pressure drops. The maximum working pressure of 250 bar in ports p, A, B, and the internal X channel permits use in medium-pressure power units common to machine tools and forming presses. The pilot stage can shift the spool once a minimum pilot pressure of 10 bar is available, guaranteeing reproducible actuation. The solenoids draw a 24 V DC supply, and the integrated electronics respond to ±10 V command signals for proportional positioning. Electrical load on the control panel remains limited because the unit consumes 30 VA when energized.

A cyclic duration factor of 100 % allows the valve to stay energized continuously without mandatory cooling pauses, which is critical for servo-controlled axes that hold position for extended periods. The enclosure meets IP65, so dust ingress and low-pressure water jets cannot affect the internal coils or electronics. Connection is made through an 11-pin plus protective-earth plug, simplifying field replacement and ensuring the ground path required for EMC compliance. The tank, X, and Y passages are also rated for 250 bar, preventing damage if back-pressure builds in return lines. A pilot valve nominal flow of 24 l/min supplies control oil to the main spool quickly, shortening response times during rapid directional changes and supporting precise flow regulation in closed-loop systems.
