Proportional Directional Valve 4WRKE27E1-500P-3X/6EG24K31/F1D3M - Bosch Rexroth R901224825

Large axes should pull hard and still set off gently, which is what spool symbol E1 is made for. The 4WRKE27E1-500P-3X with external pilot supply and external drain applies that fine control range at 500 l/min nominal flow and follows a 4...20 mA command value.

Benefits

• Spool symbol E1 blocks in centre and then opens across a fine initial range.
• 500 l/min nominal flow, 1000 l/min maximum flow, size 27.
• External pilot paths make pilot control independent of system pressure.
• A 4...20 mA current command value reveals a broken wire through the missing base current.
• 270 bar operating pressure at 19.36 kg, NBR seals for HL hydraulic fluid.
• On-board electronics at 24 VDC, 7-pole (6 + PE) plug according to EN 175201-804.

Application

The build serves main axes of presses and test rigs that demand force together with a soft start. Against the version with internal pilot routing, two extra lines have to be laid, but pilot control stays stable. Match code F1D3M when ordering a replacement.
