Proportional Directional Valve 4WRTE25E1-350P-4X/6EG24ETK31/A1M - Bosch Rexroth R901214477

Analogue cards already installed in a control system almost always put out plus or minus 10 V. The 4WRTE25E1-350P-4X/6EG24ETK31/A1M matches them without a converter, supplies and relieves its pilot stage internally and provides 350 l/min nominal flow at up to 350 bar.

Benefits

• A plus or minus 10 V command works straight off common analogue outputs, so no converter is needed.
• Internal pilot routing for supply and return leaves only four ports on the valve.
• 350 l/min nominal flow with spool symbol E1 and 3 switching positions.
• Internal spool position feedback keeps command and flow tied together.
• 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, NBR seals, 18.02 kg.

Applications

The valve runs feed axes on machine tools, die cushions and test rigs that already use analogue control. Internal pilot routing keeps piping work low. Range maximum flow of 870 l/min leaves reserve for later extensions.
