Where the working pressure of a plant is trimmed often, a rotary knob on the pump safety block is the faster answer. This block is adjustable from 3.7 to 110 bar, discharges up to 500 l/min and unloads the pump electrically at 24 VDC.

The rotary knob sets the limiting pressure between 3.7 and 110 bar without a tool. The pilot-operated pressure valve in poppet seat design holds that value, while the built-on directional spool valve takes the pressure off the pump on command.
Benefits
- Setting by rotary knob, so the limiting pressure can be changed without a tool
- Adjustment range of 3.7 to 110 bar for circuits with a low working pressure
- Electrical unloading through the built-on directional spool valve at 24 VDC
- Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
- Pressure valve in poppet seat design with a tight shut-off
- Flange connection, NBR seals for HL hydraulic fluid, CE conformity, weight of 14.22 kg
