Total price
The block sits at the pump outlet and carries out two tasks at once. The pilot-operated pressure valve in poppet seat design limits the pressure to the value set between 3.7 and 180 bar, while the built-on directional spool valve unloads the pump electrically at 24 VDC.
Benefits
- Pressure limitation and electrical unloading in one block, so separate valves and their piping are not needed
- Adjustment range of 3.7 to 180 bar at a maximum operating pressure of 350 bar
- Flow of up to 500 l/min in size 40
- Pressure valve in poppet seat design, so the seat closes tightly
- Internal hexagon with a protective cap holds the set pressure in place
- High-pressure flange connection, NBR seals for HL hydraulic fluid, weight of 14 kg
