Proportional Directional Valve 4WRKE10W8-50L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901225987

A roll gap only adjusts repeatably when the pilot stage is not dragged along by return pressure. The 4WRKE10W8-50L-3X/6EG24EK31/F1D3M therefore separates the pilot drain and works with 50 l/min nominal flow.

Benefits

• 50 l/min nominal flow, up to 170 l/min in size 10.
• Pilot oil supplied internally, drained externally, the pilot return is separated from the main return.
• 4...20 mA command with a linear characteristic curve and internal spool feedback.
• 315 bar maximum operating pressure, spool symbol W8, three switching positions.
• 8.32 kg, wired through a 7-pole (6 + PE) plug to EN 175201-804.

Technical data

Applications

The valve is used on roll adjustment, calenders and strip guides where short travels must be held accurately. It equally serves test rigs with a long return path. When exchanging a unit, keep to the same pilot variant.
