Proportional Directional Valve 4WRLE10V85M-4X/VPT/24A1 - Bosch Rexroth R901582226

The 4WRLE10V85M-4X/VPT/24A1 combines two demands that usually call for separate valves, gentle approach and fast traverse. The progressive curve with a linear fine control range keeps the opening area small around zero and releases 85 l/min at full command, 300 l/min at peak. Pilot oil is taken and returned internally, so dedicated X and Y lines are not required.

Benefits

• Progressive curve with a linear fine control range for gentle approach and fast travel.
• Nominal flow 85 l/min, maximum 300 l/min, operating pressure to 350 bar.
• Internal pilot supply and internal pilot return, which cuts piping at the valve block.
• ±10 V command value at the on-board electronics with closed loop spool position control.
• FKM seals and a valve weight of 9.4 kg on mounting pattern ISO 4401-05-05-0-05.

Application

The valve fits axes that pick up a load softly and then move it quickly, such as hoists, die cushions or roll adjustment drives. Mineral oil of class HL is intended, and the FKM seals allow higher oil temperatures. The signal line lands on a 7-pole plug to EN 175201-804.
