Description

More than a hundred metres of cable between control room and power unit is something only a current signal survives. This valve therefore works with a 4...20 mA command value and a fully external pilot circuit, at 350 l/min nominal flow.

Benefits

Command value 4...20 mA for very long signal runs, a broken wire shows as zero current
External pilot oil supply and return for a separately fed pilot circuit
Nominal flow 350 l/min, up to 870 l/min through the valve at 350 bar
Internal spool position feedback, V1 spool
On-board electronics with a 7-pole (6 + PE) connector to EN 175201-804
Weight 18.06 kg, port pattern ISO 4401-08-08-0-05

Application

The variant is used in hydropower plants, locks and large test fields where the control system sits far away. The self-contained pilot circuit can be filtered and protected independently. Operation is on HL hydraulic fluid with NBR seals at 24 VDC.

Manufacturer

Bosch Rexroth lists this valve under material number R900782489.
