Proportional Directional Valve 4WRGE10V100L-1X/315G24K31/A1WC152M - Bosch Rexroth R901460990

Once an axis has to hold a position or a speed rather than just move, accuracy depends on the feedback of the control spool. The 4WRGE10V100L-1X valve controls with internal spool position feedback at a nominal flow of 100 l/min, passes a maximum of 170 l/min and works up to 315 bar operating pressure.

Key benefits

• Internal spool position feedback, the actual spool position is controlled instead of merely commanded
• 100 l/min nominal flow and 170 l/min maximum, leaving headroom for rapid traverse and load peaks
• On-board electronics with a +/-10 V command value, no separate amplifier card in the cabinet
• External pilot oil supply and external pilot oil return, so it also works where main circuit pressure is low
• 315 bar operating pressure, mounting pattern ISO 4401-05-05-0-05, symbol V with 4 ports and 3 switching positions
• 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, NBR seals, weight 4 kg

Application

The valve drives cylinder and motor axes in presses, forming machines and test rigs that call for position or velocity control. External pilot oil supply allows installation in circuits whose pressure fluctuates too much for internal piloting. The command value arrives as a voltage signal from the higher level control system.
