Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901079372

An existing pilot pressure circuit can be put to work straight away: this valve draws pilot oil externally, releases it internally and runs at 520 l/min nominal flow up to 350 bar.

Key benefits

• External pilot oil supply uses pilot pressure that is already available, the internal return saves the Y line.
• 520 l/min nominal flow in a body released for flows up to 1600 l/min.
• Spool symbol W8 across 3 switching positions and 4 ports to ISO 4401-10-09-0-05.
• ±10 V command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• 43.7 kg installed mass, integrated pressure reducing valve, NBR seals for HL hydraulic fluid.

Applications

The variant makes sense on presses and forming lines that already run their own pilot pressure supply, for example for clamping or safety functions. Internal pilot oil return assumes a largely unloaded tank line. Operation is on HL hydraulic fluid.
