Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9TK4/M - Bosch Rexroth R901019949

In plants running their own pilot supply the main valve should use that circuit instead of depending on working pressure. The 4WRZ32E1-520-7X/6EG24N9TK4/M takes pilot oil externally, returns it internally and provides 520 l/min nominal flow.

Benefits

• External pilot oil supply from a separate circuit, pilot pressure stays independent of the load pressure on the axis.
• Internal pilot oil return, the existing tank channel is enough for relief.
• 520 l/min nominal flow, throughput up to 1600 l/min in size 32.
• Spool symbol E1, 350 bar maximum operating pressure, subplate mounting to ISO 4401-10-09-0-05.
• 43.6 kg weight, NBR seals, laid out for HL hydraulic fluid in continuous duty.

Applications

Typical plants are large presses and test rigs with a separate pilot circuit feeding several pilot-operated valves together. External supply keeps switching capability even when the working circuit briefly loses pressure. Command and supply run through a 7-pole (6 + PE) plug.
