Proportional Directional Valve 4WRZE16W6-180-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R901402387

High back pressure in the tank line throws pilot-operated valves off balance. This build of the size 16 model therefore relieves its pilot circuit through a separate external path while still feeding itself internally, at 180 l/min nominal flow and operating pressure up to 350 bar.

Benefits

• Internal supply with external pilot oil return keeps the control circuit clear of tank back pressure.
• 180 l/min nominal flow against 460 l/min maximum flow.
• Pressure reducing valve in the pilot circuit caps control pressure under 350 bar working pressure.
• Command value 4...20 mA at the on-board electronics, supply 24 VDC.
• Spool symbol W6, FKM seals, mass 12.12 kg, mounting pattern ISO 4401-07-07-0-05.

Applications

The variant belongs in plants with a heavily loaded tank return, such as press lines on a shared return header or test rigs with a filter section. Symbol W6 sets the mid position. Concealed manual override across 3 switching positions eases commissioning.
