When one tank line collects several consumers, back pressure builds up and disturbs the pilot stage. This version returns pilot oil externally through Y while still feeding itself internally from P. Size 10, 100 l/min nominal, 4...20 mA command value, 9.1 kg.

A few bar of back pressure in the return line is enough to shift the null position of a pilot-operated valve. This size 10 variant avoids that with its own pilot oil return to Y while metering 100 l/min nominal flow.
Benefits
- External pilot oil return through Y keeps the pilot stage clear of back pressure in the shared tank line.
- Internal pilot oil supply from port P saves the additional X pressure line.
- 4...20 mA command value for long cable runs, with live zero at 4 mA.
- Spool symbol V1 with fine control range, 100 l/min nominal, up to 300 l/min peak.
- Operating pressure up to 350 bar, CE conform, weight 9.1 kg.
