Proportional Directional Valve 4WRPQ6Q5-32S-3X/MGF/24SD90 - Bosch Rexroth R901521190

Over Sercos III this valve receives its command value in step with the drive controller, converting it through spool symbol Q5 into 32 l/min nominal flow at 280 bar operating pressure. Integrated flow control keeps the volume independent of the pressure differential present.

Benefits

• Sercos III with cycle-synchronous command transfer to the valve electronics
• Spool symbol Q5, direct actuation, 3 switching positions across 4 ports
• 32 l/min nominal flow at 280 bar, progressive characteristic
• Integrated flow control, 24 VDC supply through a connector, 7-pole (6 + PE)
• Compact size 6 at 4.84 kg, NBR seals, UKCA to SI2016/1091

Applications

The combination is used in machines whose motion control guides hydraulic axes alongside electrical ones. Cycle-synchronous transfer reduces scatter between cycles. A subplate to ISO 4401-03-02-0-05 is all the installation needs.

Manufacturer
