Proportional Directional Valve 4WRTE25W6-220L-4X/6EG24EK31/F1V - Bosch Rexroth R901464907

A pilot operated valve is only as reliable as its pilot oil. In the EK31 version the 4WRTE25W6-220L-4X/6EG24EK31/F1V draws that oil from an external source and therefore meters 220 l/min nominal flow at 350 bar operating pressure independently of system pressure.

Benefits

• External pilot oil supply keeps the pilot stage working when pressure in port P falls below pilot level.
• 220 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• A 4...20 mA current command survives long cable runs, and a value below 4 mA indicates a line fault.
• Spool symbol W6 across three switching positions and four ports, ISO 4401-08-08-0-05 mounting pattern.
• 350 bar operating pressure, FKM seals, 18 kg valve mass, 24 VDC supply.

Application

Intended for plants with an accumulator or several consumers working at the same time. A dedicated line has to be provided for the external pilot oil supply. The current command additionally suits long distances between cabinet and valve.
