Proportional Directional Valve 4WRKE25R350L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901377574

When a forming axis calls for a lot of oil in a short cycle, nominal flow sets the achievable speed. The 4WRKE25R350L-3X/6EG24TK31/A1D3M releases 350 l/min, works up to 350 bar and draws pilot oil from an external source, so pilot pressure stays stable even when system pressure drops.

Benefits

• 350 l/min nominal flow, 60 percent more than the 220 l/min version of the same series
• External pilot oil supply with internal return, stable pilot pressure during load changes
• Internal spool position feedback, the control deviation is corrected inside the valve
• 24 VDC supply and ±10 V command value through one connector, 7-pole (6 + PE)
• 17.82 kg valve weight in size 25, serviceable without lifting gear

Applications

Typical uses are forging presses, drawing lines and test machines with pronounced load steps. Three switching positions and four ports cover the classic cylinder circuit with P, T, A and B. The ISO 4401-08-08-0-05 pattern is standardised, so the manifold needs no rework.
