Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9EK31/A1M - Bosch Rexroth R901182702

When a valve is replaced, the signal level of the existing controller often decides the choice. This size 32 version runs on ±10 V, feeds its pilot stage internally and passes 520 l/min nominal flow at up to 350 bar.

Key benefits

• Voltage command value ±10 V into the on-board electronics, no signal converter needed
• Internal pilot oil supply with external pilot oil return, which removes one feed line from the subplate
• 520 l/min nominal flow at 350 bar in a size 32 body rated to 1600 l/min
• Mounting pattern ISO 4401-10-09-0-05, 4 ports, 3 switching positions, spool symbol W8
• 24 V DC supply through a 7-pole connector (6 + PE) to EN 175201-804, 43.6 kg

Applications

A standard pick when retrofitting presses and injection moulding machines whose controls still run on ±10 V. It also fits new builds as long as cable runs stay short. A pilot drain routed to tank without back pressure is required.
