Proportional Directional Valve 4WRLD25V400L-4X/MXY/24ED6T - Bosch Rexroth R901520720

The shorter the path between controller and valve, the steadier the axis. In this 4WRLD25V400L-4X/MXY/24ED6T the digital axis controller sits on the valve itself and manages 400 l/min nominal flow at 350 bar operating pressure, with external pilot oil supply and return.

Key benefits

• Axis controller on the valve, ±10 V command value, no extra controller card in the cabinet.
• 400 l/min nominal flow, up to 1250 l/min maximum flow in size 25.
• 350 bar operating pressure and 3 switching positions with spool symbol V.
• External pilot oil supply and external pilot oil return separate control and main circuit.
• 18.58 kg, subplate mounting to ISO 4401-08-08-0-05, 4 ports.
• NBR seals and release for HL hydraulic fluid at 24 VDC supply voltage.

Applications

The valve is intended for position-controlled large cylinders in presses, testing machines and rolling mill equipment. Where several axes run in sync, the on-valve controller shortens response time compared with a central control unit. The 12-pole connector to EN 175201-804 carries supply, command value and feedback.
