Proportional Directional Valve 4WRTE25V220L-4X/6EG24K31/A1V - Bosch Rexroth R900727843

As a replacement for an older valve with an external pilot circuit and voltage command, the 4WRTE25V220L drops onto the manifold without rework. It sets 220 l/min at operating pressures up to 350 bar.

Benefits

• Rated at 220 l/min nominal flow with a flow reserve of 870 l/min
• 350 bar maximum operating pressure leaves reserve over a 250 bar circuit
• Spool Symbol V with a linear characteristic, 3 switching positions
• External pilot oil supply and external pilot oil return, pilot operated design
• On-board electronics close the position loop themselves, so no separate amplifier is needed in the cabinet

Applications

The valve is used where an existing manifold should stay untouched and only the valve is exchanged. Because pilot oil is routed externally as before, the piping remains. At 18 kg with FKM seals it matches the common size 25 specification.
