The 4WRTE16Q2-200P-4X/6EG24ETK31/A1M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and is installed in hydraulic automation loops to proportionally meter flow and direct pressure. Its NG16 size matches manifolds using the ISO 4401-07-07-0-05 port pattern, allowing straightforward block mounting in power units. The assembly withstands operating pressures up to 350 bar and can route a recommended flow of 460 l/min, making it suitable for medium-to-high power circuits. Electronics are supplied with 24 V DC, and the spool position is commanded by a ±10 V analog signal that is accepted across an input resistance of 100 kΩ. Control accuracy is maintained when the residual ripple of the supply remains below 2.5 Vpp. System designers must account for a mass of 11.2 kg when sizing support structures and handling equipment.
A ±10 V measuring output provides feedback for closed-loop controllers that monitor actual spool displacement. Steady-state current draw does not exceed 1.6 A, while a 2.7 A impulse current is required during rapid transitions; together with a maximum power consumption of 72 VA these figures simplify fuse and cable selection. The enclosure achieves IP65 protection, enabling reliable operation in dusty or wet factory environments when the connector is properly sealed. Continuous duty is supported with a 100 % duty cycle, so the valve may remain energized without forced cooling. Hydraulic fluid cleanliness must be maintained at ISO 4406 class 18/16/13 or better to prevent wear and preserve response characteristics.
