Proportional Directional Valve 4WRZE25E1-220-7X/6EG24K31/F1M - Bosch Rexroth R901468202

In large plants many metres of cable run between cabinet and valve, and there a current signal is the more robust choice. The 4WRZE25E1-220-7X/6EG24K31/F1M therefore works with a 4 ... 20 mA command value, converts 220 l/min nominal flow and passes 870 l/min at most.

Benefits

• Command value 4 ... 20 mA, insensitive to voltage drop on long lines
• 220 l/min nominal flow, maximum flow 870 l/min in size 25
• Spool symbol E1 with three switching positions and four ports
• External pilot oil supply and external pilot oil return, piloting without a pressure reducing valve
• On-board electronics, supply voltage 24 VDC, operating pressure up to 350 bar
• Connection diagram ISO 4401-08-08-0-05, weight 20 kg

Application

The valve is used on large presses, hoists and test benches with a distant control system. The separated pilot oil routing suits plants with their own pilot pump. The operating medium is hydraulic fluid HL and the seals are NBR.
