For circuits working around 180 bar this size 40 safety block is the matching protection. It limits between 3.7 and 180 bar, takes up to 600 l/min through its high-pressure flange and unloads the pump electrically on 24 VDC, so the drive turns against no back pressure between two strokes.

Total price
A press power unit working at roughly 180 bar calls for protection set just above that level. This pilot-operated block in size 40 is set between 3.7 and 180 bar, copes with 600 l/min and depressurises the installation through its unloading solenoid.
Benefits
- Pressure setting range of 3.7 to 180 bar with internal hexagon and protective cap
- Rated flow of up to 600 l/min at an operating pressure of 350 bar maximum
- Built-on directional spool valve on 24 VDC, two switching positions and a 3-pole connector to EN 175301-803
- Pressure stage in poppet seat design, so the stage seals well at rest
- Mounted on a high-pressure flange, NBR seals and a mass of 13.95 kg
