When a machine changes between tools of different load capacity, the limiting pressure has to follow. This pump safety block carries a rotary knob for 3.7 to 150 bar and discharges up to 500 l/min.

The rotary knob sets the limiting pressure by hand between 3.7 and 150 bar without opening a cap. The pilot-operated seat valve holds that value, and the built-on directional spool valve unloads the pump at 24 VDC.
Benefits
- Rotary knob for the adjustment range of 3.7 to 150 bar, so the target can change between jobs
- Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
- Electrical unloading at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
- Pressure valve in poppet seat design with a tight shut-off
- Two ports through a high-pressure flange
- NBR seals for HL hydraulic fluid, CE conformity, weight of 13.94 kg

Applications
The block is used on power units of forming machines, clamping systems and test rigs with changing duties. The rotary knob shortens the changeover, because the new limiting pressure is entered directly. During pauses the control system leaves the circuit without pressure through the solenoid.
