Proportional Directional Valve 4WRDE10V50P-6X/MXY/24A5 - Bosch Rexroth R901562189

Accuracy here comes from the position transducer inside the valve, not from the solenoid. The 4WRDE10V50P-6X/MXY/24A5 keeps comparing actual spool position against the plus minus 10 V command value, setting 50 l/min rated flow at up to 350 bar.

Benefits

• Internal spool position feedback holds the setting under changing load, fine control range with a linear characteristic.
• 50 l/min rated flow in size 10, maximum flow of the series reaches 170 l/min.
• External pilot oil supply with external pilot return separates the pilot circuit completely from the main circuit.
• Command value plus minus 10 V at the on-board electronics, 24 V DC through the 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, 3 switching positions, 4 ports, NBR seals, 7.5 kg.

Technical data

Applications

Axes like this appear in materials testing machines, plastics machinery, servo presses where a separate pilot power unit supplies constant pilot pressure. With X as well as Y kept separate, the pilot stage stays untouched by pressure swings in the working circuit. A rated flow of 50 l/min matches medium cylinder bores at high positioning quality.
