Proportional Directional Valve 4WRKE32W6-400P-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901491808

Large cylinders need a lot of oil yet still have to position to the millimetre. The 4WRKE32W6-400P-3X/6EG24ETK31/F1D3M does both: 400 l/min nominal flow in size 32, a linear characteristic curve with a fine control range around mid position and operating pressure to 350 bar.

Benefits

• 400 l/min nominal flow, size 32 carries up to 1550 l/min.
• Linear characteristic curve with fine control range for slow approach and accurate positioning.
• 4...20 mA command value on a 24 VDC supply, on-board electronics instead of a separate card.
• Internal pilot oil supply and internal pilot oil return, no separate control lines needed.
• NBR seals, ISO 4401-10-09-0-05 interface, 37 kg.

Applications

The valve drives main axes on large presses, lifting gear and forging equipment. The fine control range helps when the tool touches down, full nominal flow serves the rapid stroke. Because pilot oil is taken internally, connecting the four main ports is enough.
