Proportional Directional Valve 4WRZE16W8-180-7X/6EG24N9K31/F1V - Bosch Rexroth R901468880

Plants with their own pilot supply set control pressure centrally. This size 16 model is built for that case, doing without a pressure reducing valve of its own, at 180 l/min nominal flow, spool symbol W8 and operating pressure up to 350 bar.

Benefits

• No pressure reducing valve in the pilot circuit, control pressure arrives from the central supply.
• External pilot oil supply plus external return, independent of working pressure up to 350 bar.
• 180 l/min nominal flow against 460 l/min maximum flow.
• Command value 4...20 mA, supply 24 VDC, spool symbol W8 across 3 switching positions.
• FKM seals, mass 12.56 kg, mounting pattern ISO 4401-07-07-0-05, conformity UKCA.

Applications

The valve fits presses as well as test rigs whose power unit carries a regulated pilot pump. Symbol W8 fixes behaviour in mid position, so it should be checked against the schematic. A concealed manual override allows the axis to be moved without electrical power.
