Proportional Directional Valve 4WRZE16E1-180-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901506455

Where a superimposed position or pressure controller already provides the accuracy, an open loop proportional valve is enough. The 4WRZE16E1-180 works without electrical main spool feedback, meters 180 l/min nominal and allows up to 460 l/min at size 16. An integrated pressure reducing valve holds pilot pressure constant even when system pressure varies across the cycle.

Benefits

• 180 l/min nominal flow with a 460 l/min limit at 350 bar.
• Pressure reducing valve in the pilot stage keeps stroke time stable despite a varying system pressure.
• Pilot oil in and out internally, only P, T, A and B are used on the subplate.
• Command value plus/minus 10 V with on-board electronics on the valve.
• Concealed manual override for commissioning and emergency motion.
• Spool symbol E1, 3 switching positions, UKCA conformity, weight 12.6 kg.

Applications

The valve sits on feed axes, lifting gear and press clamping circuits where accuracy comes from the machine position controller. It is the more economical choice over a closed loop valve as long as no high metering accuracy is demanded inside the valve itself. For axes with strict hysteresis and response requirements, Bosch Rexroth offers the 4WRLE series.
