Proportional Directional Valve 4WRTE32E1-600L-4X/6EG24EK31/F1M - Bosch Rexroth R900719150

A current signal loses none of its meaning over a long cable, a voltage signal does. The 4WRTE32E1-600L-4X/6EG24EK31/F1M therefore works with a 4 to 20 mA command, controls 600 l/min nominal flow at up to 350 bar and takes its pilot oil internally.

Benefits

• The 4 to 20 mA command stays stable over long cable runs because voltage drop does not distort a current loop.
• Nominal flow of 600 l/min against a maximum flow of 1600 l/min in size 32.
• Spool symbol E1 with 3 switching positions across 4 ports, mounting pattern ISO 4401-10-09-0-05.
• Internal pilot oil supply with external return keeps tank back pressure out of the pilot stage.
• 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, weight 37.02 kg, operating pressure up to 350 bar.

Applications

Rolling mills, continuous casting lines and hydraulic steel structures are typical, wherever the valve sits far from the cabinet. On test rigs in electrically noisy surroundings the current loop is the safer choice as well. The medium is mineral oil of class HL, sealed with NBR.
