Proportional Directional Valve 4WRZE16W6-125-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901467133

Where the control cabinet sits far from the machine, a current command value is the more robust choice. This pilot-operated size 16 valve works with 4...20 mA, releases 125 l/min nominal flow and passes up to 460 l/min at maximum.

Key benefits

• The 4...20 mA command input ignores voltage drop on long lines and shrugs off induced interference.
• 125 l/min nominal flow covers medium feed axes without pushing size 16 towards its 460 l/min limit.
• Pilot oil supply and pilot oil return are both external, keeping the control circuit separate from working pressure.
• The built-in pressure reducing valve holds pilot pressure constant across the full range up to 350 bar.
• 11.8 kg on an ISO 4401-07-07-0-05 pattern, spool symbol W6, 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve suits feed and lifting axes in the medium power range, for example saw gantries, lift tables and machine tools. A current command value pays off wherever the run between controller and valve is several metres long. NBR seals call for HL group mineral oil.
