Proportional Directional Valve 4WRLD25E400LJ-4X/MXY/24ND6T - Bosch Rexroth R901537991

A linear valve characteristic keeps loop gain constant over the whole stroke and makes controller tuning predictable. The 4WRLD25E400LJ-4X/MXY/24ND6T uses symbol E for exactly that while metering 400 l/min nominal flow at 350 bar operating pressure.

Benefits

• Symbol E, linear characteristic - even gain across the full spool stroke, three switching positions.
• Digital axis controller on the valve, command value analog ±10 V through a 12-pole connector (11 + PE) to EN 175201-804.
• 400 l/min nominal flow in size 25, up to 1250 l/min by design.
• 350 bar operating pressure across four ports, HL hydraulic fluid, NBR seals.
• External pilot oil supply and external pilot oil return for systems with their own pilot circuit.

Application

The valve works in controlled feed and press-force axes where control quality has to stay the same over the entire travel. On the ISO 4401-08-08-0-05 interface it is interchangeable with other size 25 valves. Weight is 18.58 kg.
