Proportional Directional Valve 4WRTE10V1-100P-4X/6EG24TK31/A1M - Bosch Rexroth R901023121

Replacing an existing axis means matching the spool symbol, otherwise centre position behaviour changes. The 4WRTE10V1-100P-4X/6EG24TK31/A1M carries symbol V1, delivers 100 l/min nominal flow, is fed externally through X and corrects its spool position internally, at up to 350 bar.

Benefits

• Spool symbol V1 with 3 switching positions and 100 l/min nominal flow in size 10.
• Pilot oil arrives externally through the X port and returns internally.
• Piston travel is measured inside the valve and fed back, and the characteristic curve is linear with a pronounced fine control range. Operating pressure reaches 350 bar.
• On-board electronics process the ±10 V command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, NBR seals for HL fluid, maximum flow 170 l/min, weight 9.5 kg.

Applications

The design fits presses and test rigs whose pilot supply is built separately and whose return stays pressure free. The fine control range helps with accurate approach while 100 l/min cover the fast stroke. For a replacement, component series 4X matters as much as the symbol.
