Proportional Directional Valve 4WRLD25E350SJ-4X/MPY/24ND6T - Bosch Rexroth R901474469

Creep and positioning moves are decided by resolution around centre, while rapid traverse needs full flow. The 4WRLD25E350SJ-4X/MPY/24ND6T combines both through its progressive characteristic and meters 400 l/min nominal flow at up to 280 bar operating pressure.

Benefits

• Progressive characteristic - high resolution around centre and full throughput at stroke end, three switching positions.
• Internal pilot oil supply with external pilot oil return, which removes the need for a separate pilot pressure line.
• 400 l/min nominal flow in size 25, up to 1250 l/min by design.
• 280 bar operating pressure, rated for HL hydraulic fluid with NBR seals.
• Digital axis controller on board, command value analog ±10 V through a 12-pole connector (11 + PE).

Application

The valve is at home in positioning axes with creep phases, for example joining operations, saw feeds and handling axes. The ISO 4401-08-08-0-05 interface keeps it interchangeable with the other size 25 valves. Weight is 18.58 kg.
