Proportional Directional Valve 4WRKE35E1000L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901533711

A voltage command loses measurable accuracy over twenty metres of cable, a current signal does not. The 4WRKE35E1000L-3X/6EG24TK31/F1D3M therefore works with 4...20 mA and turns that command into a nominal flow of 1000 l/min at 350 bar through its on-board electronics, with up to 3000 l/min at peak.

Benefits

• Command value 4...20 mA, insensitive to voltage drop along long cables.
• 1000 l/min nominal flow in size 35, up to 3000 l/min maximum at 350 bar operating pressure.
• External pilot oil supply with internal pilot oil return, suited to systems that hold their own pilot pressure.
• Spool symbol E with a linear characteristic curve and internal spool position feedback.
• Connection diagram ISO 4401-10-09-0-05 for subplate mounting, three switching positions across four ports.
• 69 kg weight, NBR seals for hydraulic fluid HL, 7-pole connector (6 + PE).

Applications

Flows of this order appear on large presses, forging lines and hydro power gates. External pilot oil supply helps where a dedicated pump already keeps pilot pressure constant. Before installation, check that the subplate is rated for 69 kg and for the ISO 4401-10-09-0-05 pattern.
