Proportional Directional Valve 4WRDE16V1N220P-6X/MXY/24A5 - Bosch Rexroth R901575124

A pilot-operated proportional valve replaces a switching valve plus throttle wherever speed and position have to be set steplessly. The 4WRDE16V1N220P-6X does that in size 16, at 220 l/min nominal flow, up to 460 l/min peak flow and with internal spool position feedback.

Benefits

• 220 l/min nominal flow in size 16, up to 460 l/min maximum flow.
• 350 bar operating pressure on a subplate to ISO 4401-07-07-0-05.
• Characteristic V1 with a fine control range across three switching positions, high resolution around centre.
• On-board electronics, command value ±10 V, no separate amplifier card in the cabinet.
• External pilot oil supply and return, so the pilot stage stays independent of the main circuit.
• 10.5 kg installed weight, NBR seals, HL hydraulic fluid.

Applications

Presses, injection moulding machines and test rigs are the usual place, wherever a size 16 cylinder has to travel under control. Internal position feedback keeps the spool on the command value even when load changes. The 7-pole (6 + PE) connector to EN 175201-804 links the valve straight to the machine control.
