Proportional Directional Valve 4WRKE27R3-500L-3X/6EG24K31/A1D3M - Bosch Rexroth R901266856

Where an existing analogue loop guides the axis, the valve should take the command unchanged. The 4WRKE27R3-500L-3X/6EG24K31/A1D3M accepts ±10 V directly at its on-board electronics and turns it into 500 l/min nominal flow at 270 bar operating pressure.

Benefits

• A ±10 V command input connects to existing analogue cards without a converter.
• 500 l/min nominal flow and up to 1000 l/min maximum flow at 270 bar operating pressure.
• The K31 version routes pilot oil supply and drain internally, so no extra pilot lines are needed.
• Spool symbol R3, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
• Valve mass 19.68 kg, NBR seals, HL hydraulic fluid, 24 VDC supply.

Technical data

Application

Useful when replacing older control valves in presses and test rigs built on analogue control. Internal pilot oil routing keeps the piping simple. Size 27 also feeds high volume cylinders on short cycle times.
