Besides the pressure and tank ports, this block carries a third port through which the pilot oil is drained separately. The limiting pressure can be set between 3.7 and 175 bar, and the flow reaches 550 l/min.
Benefits
- Three ports, so the pilot oil is drained independently of the tank flow
- Flow of up to 550 l/min in size 40
- Adjustment range of 3.7 to 175 bar at a maximum operating pressure of 350 bar
- Electrical unloading through the built-on directional spool valve at 24 VDC

- High-pressure flange, NBR seals for HL hydraulic fluid, CE conformity, weight of 13.82 kg
Applications
The block protects large pumps in presses, forges and steel plant where back pressure builds up in the return. The separate pilot drain keeps the response clear of it. The high-pressure flange places it directly on the pressure line.
