Proportional Directional Valve 4WRKE27E500P-3X/6EG24K31/A1D3M - Bosch Rexroth R901241021

Controllers with an analogue voltage output can drive a valve without a converter as long as it accepts ±10 V. The 4WRKE27E500P-3X does that, releases 500 l/min nominal flow and blocks all four ports in centre through spool symbol E.

Benefits

• A ±10 V command value connects straight to common analogue outputs, no converter needed.
• Spool symbol E blocks the axis in centre and secures the load if the signal fails.
• 500 l/min nominal flow and 1000 l/min maximum flow in size 27.
• External pilot oil supply and drain for plants with their own pilot supply.
• 270 bar operating pressure at 19.35 kg mass with NBR seals.
• Pilot operated design with internal spool position feedback for repeatable positions.

Application

The valve is at home on main axes of forming plants and large test rigs whose host controller issues analogue voltage signals. Spool symbol E is the right choice when the axis must stay put without a signal. Code A1D3M tells the build apart from the F1D3M versions of the same series.
