Proportional Directional Valve 4WRGE25V1-350L-1X/315G24ETK31/A1M - Bosch Rexroth R900954162

An axis tracks its command only as closely as the valve knows its own spool position. The 4WRGE25V1-350L-1X/315G24ETK31/A1M reports spool position electrically, follows a linear characteristic curve and meters 350 l/min nominal flow with spool symbol V1.

Benefits

• Electrical spool position feedback with a linear characteristic across the control range up to 350 l/min
• 350 l/min nominal flow, max. flow 870 l/min in size 25
• Maximum operating pressure 350 bar, interface ISO 4401-08-08-0-05
• Internal pilot oil supply and internal pilot oil return, so the manifold needs neither an X nor a Y line
• On-board electronics for the ±10 V command, 24 VDC supply through a 7-pole connector (6 + PE)
• 3 switching positions, 4 ports, NBR seals for HL hydraulic fluid, weight 16.68 kg

Applications

The valve controls position-regulated cylinder and motor axes in presses, test rigs and forming lines where the position matters more than the sheer flow rate. Because pilot supply and pilot return stay inside the valve, it mounts on an existing manifold to ISO 4401-08-08-0-05 without extra control lines. The NBR seals are released for HL hydraulic fluid.
