Proportional Directional Valve 4WRZ32W9-520-7X/6EG24N9K4/M - Bosch Rexroth R900719890

A separate pilot circuit pays off as soon as working pressure swings hard. The 4WRZ32W9-520-7X/6EG24N9K4/M is laid out to take pilot oil from outside and give it back outside, metering 520 l/min nominal flow regardless of what the main circuit is doing.

Key benefits

• External pilot oil supply and external return keep pilot pressure constant.
• 520 l/min nominal flow, maximum flow 1600 l/min, operating pressure up to 350 bar.
• Spool symbol W9 with 3 switching positions and 4 ports, connection pattern ISO 4401-10-09-0-05.
• Concealed manual override, version without pilot pressure reducing valve.
• 43.1 kg weight in size 32, NBR seals for HL hydraulic fluid.
• Driven by external electronics, 24 VDC supply, 3-pole connector (2 + PE).

Applications

Intended for press lines and forming plants whose working pressure collapses and rebuilds every cycle. A separate pilot supply keeps the step response identical throughout. With 520 l/min nominal flow the valve moves even large main cylinders in a short time.
