Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24K31/F1V - Bosch Rexroth R901291877

On axes fed from a central pilot circuit the valve should neither draw control oil from working pressure nor drain into the return. The 4WRTE10W8-50L-4X/6EG24K31/F1V is supplied and drained externally and meters 50 l/min nominal flow on a linear curve at up to 350 bar.

Benefits

• Spool symbol W8 with 3 switching positions and 50 l/min nominal flow in size 10.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• Piston travel is measured inside the valve and fed back, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• On-board electronics process the 4...20 mA command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, FKM seals for HL fluid, maximum flow 170 l/min, weight 8.38 kg.

Technical data

Applications

It is used in test fields, forming plants and special machines with their own pilot pump and warm operating medium. The linear characteristic keeps loop gain constant across the stroke. X and Y ports have to be provided in the subplate.
