Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9ETK31/F1M - Bosch Rexroth R900739911

Assembly time is saved by not piping anything that is not strictly needed. This size 32 build works with internal pilot oil in both directions and controls 520 l/min nominal flow at up to 350 bar from a current signal.

Key benefits

• Internal pilot oil supply and internal pilot oil return, only 4 main ports to pipe
• Current command value 4 to 20 mA, robust even over long cable runs
• 520 l/min nominal flow, with the size 32 body permitting 1600 l/min
• 350 bar operating pressure, mounting pattern ISO 4401-10-09-0-05, 3 switching positions
• Spool symbol W8, 24 V DC supply, weight 43.46 kg, UKCA to SI2016/1091

Applications

A fit for series machines whose valve block has to be assembled inside a short takt time. System pressure also feeds the pilot stage, so a minimum pressure has to be maintained. The tank port should be sized for low back pressure.
