Proportional Directional Valve 4WRKE35E1000L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901261685

Every extra pilot line is one more fitting, one more assembly step and one more thing to get wrong during commissioning. The 4WRKE35E1000L-3X/6EG24ETK31/F1D3M does without them, because pilot oil supply and pilot oil return run internally. What remains are the four main ports carrying 1000 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no additional pilot lines on the manifold.
• 1000 l/min nominal flow, up to 3000 l/min maximum, at 350 bar operating pressure in size 35.
• Spool symbol E with a linear characteristic curve and internal spool position feedback.
• Command value 4...20 mA through on-board electronics, so no external amplifier card is needed.
• Connection diagram ISO 4401-10-09-0-05 for subplate mounting, 69.8 kg, NBR seals for hydraulic fluid HL.

Applications

The build suits manifolds whose main circuit always carries enough pilot pressure and whose tank gallery is generously sized. Presses, forging manipulators and large test cylinders are typical applications. With all pilot paths inside the valve, installation comes down to the four main ports and the 7-pole connector.
