Proportional Directional Valve 4WRDE10V1-50L-6X/MPY/24A5 - Bosch Rexroth R901521700

A size 10 axis can only be moved smoothly in position and speed when the main spool reports its own position back. On that basis the 4WRDE10V1-50L-6X/MPY/24A5 meters 50 l/min nominal flow at a maximum operating pressure of 350 bar, with internal pilot oil supply and external pilot oil return.

Benefits

• 50 l/min nominal flow with up to 170 l/min maximum flow for short rapid strokes.
• Maximum operating pressure 350 bar in size 10, mounting pattern ISO 4401-05-05-0-05.
• Internal pilot oil supply from the pressure port, external return through the Y line.
• Spool symbol V1 with 3 switching positions on 4 ports and internal spool position feedback.
• On-board electronics, ±10 V command value at 24 VDC, 7-pole connector (6 + PE) according to EN 175201-804.
• 7.5 kg installed weight, NBR seals, HL hydraulic fluid.

Technical data

Applications

Intended for feed and positioning axes on machine tools, presses and test benches with subplate mounting to ISO 4401-05-05-0-05. The external pilot drain suits power units whose main return line builds up back pressure across cooler and filter. At 50 l/min nominal flow the valve covers medium cylinder sizes, and 170 l/min maximum flow leaves headroom for fast travel.
