Total price
A constant pilot pressure makes the behaviour of a proportional valve repeatable. This version achieves it with a built in pressure reducing valve and drives the main spool to symbol E. At a nominal flow of 85 l/min, 170 l/min flow at maximum.
Benefits
- Symbol E in 3 switching positions at a nominal flow of 85 l/min
- Pressure reducing valve in the pilot stage for consistent switching behaviour
- Maximum flow 170 l/min at an operating pressure of up to 315 bar
- Internal pilot oil supply and internal pilot oil return
- Driven from external electronics to EN 175201-804
- NBR seals for HL hydraulic fluid, mass 8.2 kg
