Proportional Directional Valve 4WRZE25W8-220-7X/6EG24EK31/F1M - Bosch Rexroth R901003252

Two common requirements meet here, a current command value and a return without back pressure on the piloting. The 4WRZE25W8-220-7X/6EG24EK31/F1M satisfies both, works at 220 l/min nominal flow and weighs 20.2 kg.

Benefits

• Command value 4 ... 20 mA, robust against interference on the signal line
• Internal pilot oil supply with external pilot oil return
• 220 l/min nominal flow, maximum flow 870 l/min
• Spool symbol W8 with three switching positions
• On-board electronics, supply voltage 24 VDC, operating pressure 350 bar
• Connection diagram ISO 4401-08-08-0-05, weight 20.2 kg

Application

Suited to presses, hoists and test benches with a filter or cooler in the return and a long signal run. Internal pilot oil pick-up saves a pressure line. Hydraulic fluid HL is intended and the seals are made of NBR.
