Proportional Directional Valve 4WRLD16Q3-200M-4X/MXY/24ED6T - Bosch Rexroth R901472450

Positioning tasks on presses, test rigs and forming machines need a valve that does not just move the spool but knows where it stands. The 4WRLD16Q3-200M-4X/MXY/24ED6T measures spool position internally and corrects it through the built-in digital axis controller, at 250 l/min nominal flow and 350 bar operating pressure.

Key benefits

• Internal spool position feedback plus digital axis controller close the loop inside the valve, so no extra control electronics are required in the cabinet.
• Progressive characteristic with a linear fine control range gives high resolution around mid position and still reaches 800 l/min at full stroke.
• External pilot oil supply and external pilot oil return keep the control circuit separate from the working circuit, even when the main circuit runs unpressurised.
• Connection diagram ISO 4401-07-07-0-05 with subplate mounting fits existing size 16 subplates without rework.
• A 12-pole connector (11 + PE) to EN 175201-804 carries the 24 VDC supply, the command value and diagnostics through one cable.

Applications

The typical application is any cylinder that has to reach and hold a target position, for example press slides, bending axes or material testing machines. The fine control range around mid position allows slow approach, while full stroke with 800 l/min covers the fast return. Mineral oil of category HL is the intended fluid, and the NBR seals define the permitted temperature range.
