Proportional Directional Valve 4WRZ32E520-7X/6EG24N9TK4/V - Bosch Rexroth R901464904

If pilot oil comes from a circuit of its own while the return heads into the tank channel anyway, draining internally saves a line. The 4WRZ32E520-7X/6EG24N9TK4/V is built that way, works with spool symbol E and provides 520 l/min nominal flow.

Key benefits

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

Applications

The variant works in main axes of presses and hoists whose power unit carries a pilot pump. Spool symbol E defines a specific behaviour in mid position while the axis is at rest. At 520 l/min nominal flow there is still headroom up to the maximum flow of 1600 l/min.
