Proportional Directional Valve 4WRZE25W8-325-7X/6EG24K31/A1D3M - Bosch Rexroth R901109701

A separate pilot oil circuit keeps the response time of a directional valve independent of working pressure. The 4WRZE25W8-325-7X/6EG24K31/A1D3M is built external on both feed and return for that, metering 325 l/min nominal flow at 350 bar.

Benefits

• External pilot oil supply and external pilot oil return fully decouple pilot control from the working circuit.
• 325 l/min nominal flow with reserve up to 870 l/min maximum flow.
• Analog ±10 V command carries direction in its sign, so one line covers both movements.
• The integrated pressure reducing valve protects the pilot stage against excessive control pressure.
• Spool symbol W8, three switching positions, four ports, mounting pattern ISO 4401-08-08-0-05.

Applications

Suited to press lines and test rigs where several valves share one pilot oil supply. The external return keeps pilot control free of back pressure from filters and coolers. UKCA conformity to SI2016/1091.
