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.

Manufacturer

Bosch Rexroth, material number R901377869, type 4WRTE25E220L-4X/6EG24K31/F1M, component series 4X.
