Proportional Directional Valve 4WRZE16E3-150-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901470133

Where the command line runs through electrically noisy surroundings, a current signal is the safe choice. This 4WRZE16E3-150 accepts 4...20 mA, meters 150 l/min nominal from it and allows up to 460 l/min at size 16. Pilot oil is routed entirely internally, so the valve needs no separate X or Y piping at the subplate.

Benefits

• Command value 4...20 mA, the 4 mA live zero separates a broken wire from a zero command.
• 150 l/min nominal flow, valve limit 460 l/min.
• Internal pilot supply and internal pilot return save two pipe runs per mounting position.
• On-board electronics powered from 24 VDC, with no extra control card in the cabinet.
• Operating pressure 350 bar with NBR seals for HL mineral oil.
• Port pattern ISO 4401-07-07-0-05 fits any standard size 16 subplate.

Applications

The valve serves feed axes, lifting cylinders and winder drives that run under control in both directions. Because pilot oil is taken and returned internally, it suits compact manifolds without a dedicated pilot circuit. The concealed manual override lets the axis be moved during commissioning or after a power failure.
