Proportional Directional Valve 4WRDE16V1-150L-6X/MXY/24A5 - Bosch Rexroth R901481789

When both working pressure and tank back pressure are unsteady, only full separation helps. The 4WRDE16V1-150L-6X/MXY/24A5 feeds its pilot stage through X from a dedicated circuit and drains the pilot oil separately to tank through Y. The main spool with symbol V1 delivers 150 l/min nominal flow under closed loop control by the internal position transducer.

Benefits

• External pilot oil supply and external return separate the pilot stage completely from the main circuit.
• 150 l/min nominal flow with short term peaks of up to 460 l/min.
• Spool symbol V1 with three switching positions up to an operating pressure of 350 bar.
• Closed loop main spool with an analogue ±10 V command value and no separate amplifier.
• Valve weight 10.5 kg on an ISO 4401-07-07-0-05 mounting pattern.

Application

This piping arrangement belongs on axes that have to hold position accurately around zero, for example test rigs and control presses with their own pilot pump. The fluid is mineral oil of class HL and the seals are NBR. The plug is 7-pole to EN 175201-804.
