Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9TK4/M - Bosch Rexroth R901069038

Where a separate pilot circuit exists but the return line stays unpressurised, external supply with internal return is enough. This size 10 valve is built that way and works at a nominal flow of 50 l/min to symbol W8, up to 170 l/min at maximum.

Benefits

• External pilot oil supply with internal pilot oil return, only one extra connection
• Nominal flow 50 l/min, maximum flow 170 l/min
• Symbol W8 in 3 switching positions across 4 ports
• Concealed auxiliary actuation for commissioning
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05
• NBR seals for HL hydraulic fluid, mass 7.76 kg

Applications

The valve is installed in machine tools and presses with a separate pilot circuit. The steady pilot pressure gives predictable switching times even when working pressure fluctuates.
