Proportional Directional Valve 4WRTE25E220L-4X/6EG24K31/F1M - Bosch Rexroth R901377869

Bosch Rexroth ✓ Original product Brand new Made in Germany

A separate, pressure stable pilot supply keeps the pilot stage independent of a fluctuating working pressure. This 4WRTE25E220L-4X uses external supply and external return, at 220 l/min nominal flow with a 4 to 20 mA command value.

Description

When working pressure collapses during a load change, an internally supplied pilot stage briefly loses actuating force. The 4WRTE25E220L-4X with external pilot oil supply and external return avoids this and keeps controlling at 220 l/min nominal flow, at 350 bar operating pressure.

Benefits

  • External pilot oil supply and external pilot oil return, decoupled from the working circuit
  • 220 l/min nominal flow, 870 l/min maximum flow, 350 bar operating pressure
  • Spool symbol E with three switching positions and four ports
  • Analog 4 to 20 mA command value, on-board electronics, 24 VDC
  • ISO 4401-08-08-0-05 interface, NBR seals

Applications

Sensible in installations with strongly changing load, for example forging hammers, shears and drawing presses. A small pilot power unit then supplies several valves with constant pilot pressure. The external return likewise prevents back pressure in the tank line from acting on the pilot stage.
