The 4WRTE16V200P-4X/6EG24ETK31/A5M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and regulates hydraulic flow and pressure in automated circuits. Its nominal size of 16 supports medium-to-high flow rates, while a mounting pattern conforming to ISO 4401-07-07-0-05 allows direct installation on standardized subplates. The unit withstands system pressures up to 350 bar on ports p, a, and b, enabling use in high-pressure servo loops. Internal pilot supply and return, marked as the ET configuration, eliminate external pilot lines, and a pilot oil flow of 14 l/min at 315 bar ensures precise spool control across the full command range. An IP65 housing shields the electronics from dust and water spray, making cabinet sealing unnecessary in most plant environments.
The A5 control interface accepts a ±10 V command signal with an enable line, providing analog position input to the integrated electronics. The valve operates from a 24 VDC supply, with functional limits from 18 VDC to 35 VDC to tolerate line variation; maximum current draw reaches 1.6 A, and overall power consumption does not exceed 72 VA, so a compact power supply is sufficient. Continuous energization is supported by a 100 percent duty cycle, ensuring the spool can stay under electronic control without thermal pauses. Electrical connection is made through a K31 plug per DIN EN 175201-804 for quick replacement in the field. NBR seals maintain compatibility with conventional mineral hydraulic oils, and an 11.2 kg mass requires a rigid manifold or mounting plate to prevent vibration during dynamic operation.
