An existing subplate without X and Y bores narrows the choice considerably. This valve feeds its pilot circuit internally and accepts a 4 to 20 mA current command. It supplies 520 l/min nominal flow at up to 350 bar and weighs 44 kg.

A subplate without X and Y bores only accepts valves with an internal pilot path, which is what this version offers at 520 l/min nominal flow on a 4 to 20 mA current command.
Key benefits
- Pilot oil supplied and returned internally, so the existing subplate needs no additional bores.
- 4 to 20 mA current command with detectable wire break, supplied from 24 VDC.
- 520 l/min nominal flow in a body rated for a maximum flow of 1600 l/min.
- Spool symbol W8 with 3 switching positions and 4 ports to ISO 4401-10-09-0-05.
- 44 kg installed mass, integrated pressure reducing valve, NBR seals on HL hydraulic fluid.
