Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9TK4/V - Bosch Rexroth R900954548

When an existing station is rebuilt, the pilot feed line is usually already laid while a second port is rarely free. The 4WRZ32W6-520-7X/6EG24N9TK4/V takes pilot oil from outside and drains it internally, at 520 l/min nominal flow with spool symbol W6.

Key benefits

• External pilot oil supply with internal return, the existing pilot line stays usable.
• 520 l/min nominal flow, maximum flow 1600 l/min, operating pressure up to 350 bar.
• Spool symbol W6, 3 switching positions, 4 ports, connection pattern ISO 4401-10-09-0-05.
• 43.12 kg weight in size 32, FKM seals, HL hydraulic fluid.
• Concealed manual override, version without pilot pressure reducing valve.
• Driven by external electronics, 24 VDC supply, 3-pole connector (2 + PE).

Applications

The variant proves itself when modernising older presses whose pilot supply is to be kept. Symbol W6 allows fine metering on approach before the axis goes to rapid travel at 520 l/min. An internal return saves rebuilding the tank lines.
