A separate pilot line costs assembly time and adds another possible leak point. This size 32 valve with spool symbol W8 draws pilot oil internally from the pressure port and drains it externally. It controls 520 l/min nominal flow at 350 bar from a 4 to 20 mA command value.

Every extra pilot line on the subplate is one more joint that has to stay tight. This size 32 version feeds its pilot stage internally from main pressure and only needs the return line, at 520 l/min nominal flow and up to 350 bar.
Key benefits
- Internal pilot oil supply from the pressure port, only the pilot oil return is routed externally
- 520 l/min nominal flow in a size 32 body with 1600 l/min of headroom
- Current command value 4 to 20 mA into the on-board electronics, 24 V DC supply
- 350 bar operating pressure on mounting pattern ISO 4401-10-09-0-05, 3 switching positions, 4 ports
- Spool symbol W8, concealed manual override, 43.8 kg

Applications
A sound choice wherever the main circuit always carries enough pressure for the pilot stage, for example on presses held at standing system pressure. The pilot drain has to run to tank without back pressure. If system pressure collapses in operation, the pilot stage loses its supply as well.
