Description
The fewer external lines a valve needs, the faster the manifold is piped. This version works entirely with internal pilot oil and transfers 350 l/min nominal flow at 350 bar in size 25.
Benefits
- Internal pilot oil supply and internal return, only P, A, B and T have to be piped.
- 350 l/min nominal flow at 350 bar, flow up to 870 l/min.
- Spool symbol W8 with 3 switching positions across four ports.
- ±10 V command value, on-board electronics with internal spool position feedback.
- 18.06 kg installed weight, NBR seals for HL fluid.
Applications
Typical for standard presses, log saws and drawing lines with sufficiently high system pressure. System pressure has to stay above the minimum pilot pressure at all times, otherwise the version with external supply is the right choice. Connection diagram ISO 4401-08-08-0-05.
