Proportional Directional Valve 4WRTE16E150L-4X/6EG24ETK31/F1M - Bosch Rexroth R901568335

In large plants thirty metres of cable between cabinet and valve are common, and a voltage signal loses accuracy along the way. The 4WRTE16E150L-4X/6EG24ETK31/F1M therefore works with a 4 to 20 mA current command and converts it into 150 l/min nominal flow.

Benefits

• Command value 4 to 20 mA, insensitive to voltage drop on long lines.
• 150 l/min nominal flow in size 16, up to 460 l/min maximum.
• Spool symbol E with a linear characteristic, internal spool position feedback.
• On-board electronics at 24 V DC, no separate amplifier in the cabinet.
• 350 bar maximum operating pressure at 11.8 kg weight, connection diagram ISO 4401-07-07-0-05.

Applications

The valve drives cylinder and motor axes in presses, test benches and rolling mills with analog control systems. Pilot oil supply and return are routed internally, which saves two external lines. Four ports and three switching positions serve a double acting cylinder.

Manufacturer

Bosch Rexroth, material number R901568335, product family 4WRTE. The electrical connection is a connector, 7-pole (6 + PE) according to EN 175201-804, and the electronics sit inside the valve.
