Proportional Directional Valve 4WRZE16W8-180-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901416414

This build of the 4WRZE16 series combines a high nominal flow of 180 l/min with a 4...20 mA current command value. Pilot oil is fed and drained internally, so only the main ports have to be piped at the valve block, at up to 350 bar operating pressure.

Benefits

• 180 l/min nominal flow at 460 l/min maximum flow for fast large axes.
• A 4...20 mA current command value is insensitive to voltage drop on long cables.
• Internal pilot oil routing on both sides reduces the number of pipe runs.
• The built-in pressure reducing valve secures constant pilot pressure across the whole pressure range.
• On-board electronics at 24 VDC, connected through a 7-pole (6 + PE) plug according to EN 175201-804.
• 12.6 kg mass and FKM seals, UKCA compliant under SI2016/1091.

Application

The version serves presses and lifting gear whose axes shift large oil volumes in short time. Spool symbol W8 blocks in centre and holds the load if the signal fails. Before swapping against the build with external pilot oil return, check the piping.
