Proportional Directional Valve 4WRZE10E85-7X/6EG24N9TK31/A1V - Bosch Rexroth R901505822

Some power units carry a pilot pump but no separate drain line for pilot oil. The 4WRZE10E85-7X/6EG24N9TK31/A1V is plumbed for exactly that case, taking pilot oil from outside and draining it internally, at 85 l/min nominal flow and operating pressures up to 315 bar.

Benefits

• External pilot oil supply combined with internal pilot oil return, one control line fewer in the manifold.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol E, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• FKM seals for HL hydraulic fluid, 8.58 kg weight.
• On-board electronics, ±10 V command value, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.
• Concealed auxiliary actuation for commissioning and fault finding without a signal source.

Applications

The valve is used on forming presses and plastics machinery whose power unit carries a small pilot pump. The internal pilot drain saves the Y line, while the external supply keeps pilot pressure independent of working pressure. FKM seals allow higher oil temperatures in continuous duty.
