Not every circuit should go beyond 100 bar, and there is a matching pressure stage for that. The pilot-operated DBW20B2-5X limits within a range of 4 to 100 bar, carries FKM seals and relieves up to 500 l/min in size 25.

Clamping, holding and feeding circuits do not need full system pressure, they need a cleanly limited stage. The pilot-operated pressure relief valve DBW20B2-5X/100S6SMG24N9K4B12V sets it between 4 and 100 bar and relieves up to 500 l/min.
Benefits
- Setting range 4 to 100 bar for circuits working below system pressure.
- Internal hexagon with protective cap, the setting stays put after commissioning.
- Up to 500 l/min in size 25 to port pattern ISO 6264-08-13.
- FKM seals, HL hydraulic fluid, weight 6.08 kg.
- 24 VDC solenoid, two ports, maximum operating pressure 350 bar.

Application
In workpiece clamping and feed units this valve caps the sub-circuit at a value the part can take. The rest of the machine keeps running at full pump pressure. The solenoid unloads the sub-circuit electrically when the clamping force is to stay applied.
