Proportional Directional Valve 4WRTE10E100P-4X/6EG24K31/F1M - Bosch Rexroth R900766618

A separate pilot circuit costs a pump but gives the pilot stage a constant pressure. The 4WRTE10E100P-4X/6EG24K31/F1M uses that consistently: pilot oil from outside, return to outside, 100 l/min nominal flow and a 4...20 mA setpoint.

Key benefits

• External pilot oil supply and external return keep pilot pressure constant.
• 100 l/min nominal flow in size 10, maximum flow 170 l/min.
• A 4...20 mA setpoint, 24 VDC supply, electronics integrated in the valve.
• Spool symbol E, 3 switching positions, 4 ports, connection pattern ISO 4401-05-05-0-05.
• Linear characteristic curve with fine control range, operating pressure up to 350 bar.
• 9 kg weight, NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

The valve suits test and production plants whose working pressure changes strongly within a cycle. Because the pilot stage draws from a circuit of its own, the step response stays the same throughout. Nominal flow of 100 l/min matches cylinders of medium piston area.
