Proportional Directional Valve 4WRDE16V1-220L-6X/MXT/24A5 - Bosch Rexroth R901560002

External pilot oil supply combined with internal pilot oil return makes the 4WRDE16V1-220L-6X/MXT/24A5 useful where working pressure fluctuates strongly and the pilot stage still has to be fed at a steady level. The main spool delivers 220 l/min nominal flow, up to 460 l/min is possible for short periods, and the on-board electronics track the spool position through the transducer.

Benefits

• External pilot oil supply decouples the pilot stage from pressure drops in the main circuit.
• Internal pilot oil return saves the separate Y line to tank.
• Nominal flow 220 l/min and a maximum flow of 460 l/min at up to 350 bar.
• Spool symbol V1 with three switching positions and a linear characteristic curve.
• Command value of ±10 V at the on-board electronics, valve weight 10.5 kg.

Application

This version is used on presses, injection moulding machines and rolling mill axes with a high flow demand. The subplate pattern follows ISO 4401-07-07-0-05. The NBR seals suit mineral oil of class HL and the plug is 7-pole to EN 175201-804.
