Proportional Directional Valve 4WRTE25V1-350L-4X/6EG24TK31/A1M - Bosch Rexroth R900954293

A dedicated small pilot power unit keeps pilot pressure constant even when the main circuit collapses. This build with external pilot oil supply makes use of that and meters 350 l/min nominal flow through its V1 spool.

Benefits

• External pilot oil supply for feeding from a separate pilot power unit
• Internal return, so only one extra line is required
• Nominal flow 350 l/min at an operating pressure of 350 bar
• Internal spool position feedback instead of a fixed characteristic
• Command value ±10 V, V1 spool, four ports
• Weight 17.85 kg, port pattern ISO 4401-08-08-0-05

Application

The valve is used in plants whose main pressure fluctuates heavily, such as forging presses and steelworks cranes. A separately fed pilot circuit maintains control quality through pressure dips. Operation is on HL hydraulic fluid with NBR seals at 24 VDC.
