Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9TK31/F1M - Bosch Rexroth R901116103

The 4WRZE10W6-85-7X/6EG24N9TK31/F1M combines 85 l/min nominal flow with external pilot oil supply and internal pilot oil return. Maximum operating pressure is 315 bar and peaks of 170 l/min are possible.

Advantages

• Nominal flow 85 l/min, maximum flow 170 l/min, operating pressure to 315 bar
• External pilot oil supply from a safeguarded circuit, internal pilot oil return
• W6 spool, 3 switching positions, 4 ports
• Concealed auxiliary actuation, built without a pressure reducing valve
• On-board electronics, 4 to 20 mA command value, 24 V DC supply
• UKCA under SI2016/1091, weight 8.48 kg, NBR seals

Applications

The combination fits power units with an accumulator or a dedicated pilot pump, where main pressure swings during the cycle. At 85 l/min the valve serves cylinders in presses and lifting gear. An internal pilot drain saves a line in the manifold.

Manufacturer
