Proportional Directional Valve 4WRKE25W8-350L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R900743953

A rapid stroke of 350 l/min has to be controlled without additional piping. In version ETK the 4WRKE25W8-350L-3X takes pilot oil internally and returns it internally, while the command value reaches the on-board electronics as a 4...20 mA current signal. Operating pressure may reach 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no X or Y line
• 350 l/min nominal flow, flow rate up to 870 l/min
• 4...20 mA current command value, 24 V DC supply
• Spool symbol W8, three switching positions, four ports
• 17.6 kg weight, operating pressure up to 350 bar, NBR seals

Applications

The valve is installed on control manifolds of presses, forging plants and lifting gear. Because pilot stage and main stage share one circuit, the piping stays simple. For that the tank line should remain largely free of pressure.
