Description
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
Applications
The block sits on circulation pumps, cooling and filter circuits and on the prefill systems of large presses. There it protects coolers and filters whose permitted pressure lies far below that of the main circuit. Electrical unloading takes the pressure off the circuit while the plant stands.
