Proportional Directional Valve 4WRPE10E1-80SJ-3X/V/24A1 - Bosch Rexroth R901437493

The 4WRPE10E1-80SJ moves cylinders and motors at 80 l/min nominal flow up to 350 bar and is meant for machines where an additional ISA adapter handles the safety shut-down. Internal spool position feedback holds the spool to the command value, which the on-board electronics accept as a ±10 V voltage signal. Spool symbol E1 works across three switching positions and four ports.

Benefits

• 80 l/min nominal flow in size 10 at up to 350 bar operating pressure
• Safety shut-down through an additional ISA adapter, which is why the hole pattern is ISO 4401-05-04-0-94
• Internal spool position feedback for closed-loop spool travel
• On-board electronics, ±10 V command value input, 24 VDC supply
• Spool symbol E1, three switching positions, four ports
• FKM seals for HL hydraulic fluid, 7.8 kg unit weight, CE conformity

Application

The valve is built for machines with a safety requirement on the axis, such as presses, stamping units and handling equipment, where the ISA adapter isolates the hydraulic branch in a fault. It is direct operated and therefore needs no pilot circuit. The ISO 4401-05-04-0-94 interface differs from the standard size 10 pattern and must be taken into account when choosing the subplate.
