Proportional Directional Valve 4WRTE27E500L-4X/6EG24K31/A1M - Bosch Rexroth R900616822

When the control valve of a lifting axis fails, the matching arrangement of the replacement matters most. The 4WRTE27E500L-4X/6EG24K31/A1M routes both pilot paths to the outside, works with a ±10 V command value and meters 500 l/min nominal flow in size 27.

Benefits

• Both pilot paths external, matching power units with a separate control oil pump.
• A ±10 V command value with on-board electronics replaces an external amplifier.
• Nominal flow 500 l/min at 270 bar, maximum flow 1000 l/min.
• Spool symbol E, 3 switching positions, 4 ports, connection diagram ISO 4401-08-07-0-05.
• Weight 19.45 kg, NBR seals, supply 24 V DC through a 7-pole connector (6 + PE).

Applications

The valve works in lifting gear, swing drives and medium to large presses. The combination of spool symbol E with external pilot routing matches the classic layout of many older plants. The existing subplate to ISO 4401-08-07-0-05 is enough for the exchange.
