Proportional Directional Valve 4WRZE16W6-180-7X/6EG24ETK31/A1D3M - Bosch Rexroth R901373448

Whether a cylinder is held or relieved in mid position is decided by the spool symbol. The 4WRZE16W6-180-7X carries symbol W6, meters 180 l/min nominal flow at up to 350 bar and feeds and drains pilot oil internally.

Benefits

• Spool symbol W6 with three switching positions for applications that should relieve in the centre.
• Internal pilot oil supply and internal return save two control lines on the manifold.
• 180 l/min nominal flow in size 16, range maximum flow up to 460 l/min.
• Plus or minus 10 V command, on-board electronics, 24 VDC supply at a 7-pole connector (6 + PE) to EN 175201-804.
• Operating pressure to 350 bar, mounting pattern ISO 4401-07-07-0-05, weight 12.56 kg.

Applications

This build suits axes where the cylinder should stand unstressed after a stop, for instance on clamping fixtures and forming tools. The pressure reducing valve in the pilot circuit keeps the pilot stage steady even as working pressure changes. NBR seals match mineral oil of class HL.
