A short spring characteristic makes the limiting pressure easy to set finely between 3.7 and 55 bar. The pilot-operated seat valve holds the value while the built-on spool takes the pressure off the pump on command.
Benefits
- Adjustment range of 3.7 to 55 bar, matched to circuits with a very low working pressure
- Flow of up to 500 l/min in size 40
- Maximum operating pressure of the block is 350 bar, independent of the set limit
- Poppet seat design of the pressure valve for a tight shut-off
- Internal hexagon with a protective cap, electrical unloading at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
- High-pressure flange, NBR seals, CE conformity, weight of 13.34 kg
