Proportional Directional Valve 4WRTE32W8-400L-4X/6EG24ETK31/F1M - Bosch Rexroth R901287893

In large plants twenty metres of cable between cabinet and manifold are quickly reached. The 4WRTE32W8-400L-4X therefore takes its command as a 4 to 20 mA current and controls 400 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA current command, unaffected by voltage drop over long cable runs.
• 400 l/min nominal flow, up to 1600 l/min maximum flow in size 32.
• Internal pilot oil supply and internal return, no additional control oil lines required.
• Symbol W8 with a linear characteristic and internal piston position feedback.
• 32 kg weight at 350 bar operating pressure, NBR seals, 7-pole connector (6 + PE).

Applications

A match for widely spread installations such as rolling mills, hydraulic engineering and metallurgical plants where control and valve sit far apart. Internal piloting keeps the piping on the control block simple. HL is the specified fluid.
