Proportional Directional Valve 4WRTE25V350L-4X/6EG24EK31/A1M - Bosch Rexroth R900970876

A position-controlled spool holds its place even as flow forces rise. The 4WRTE25V350L-4X measures spool position inside the valve and corrects it continuously while metering 350 l/min nominal flow at up to 350 bar operating pressure.

Benefits

• Internal position feedback with a linear characteristic, spool position tracks the command repeatably.
• Nominal flow of 350 l/min, maximum flow 870 l/min.
• Voltage command ±10 V with on-board electronics, supplied at 24 VDC.
• Internal pilot supply with external drain for circuits carrying back pressure in the tank line.
• Spool symbol V, three switching positions, connection diagram ISO 4401-08-08-0-05.
• Mass of 17.88 kg with NBR seals, HL hydraulic fluid.

Application

The controlled build goes onto axes running position or velocity control, for example feeds on forming machines and test cylinders following a set motion profile. The external pilot drain calls for a Y port routed to tank without back pressure. A 7-pole (6 + PE) connector to EN 175201-804 covers the electrical side.
