Accumulator circuits are often run at a 210 bar cut-off. The DBW20B2-5X/210Y hits that value inside a 4 to 210 bar setting range, relieves 450 l/min and unloads the pump through a 24 VDC solenoid. Weight is 5.36 kg.

The DBW20B2-5X/210Y6EG24N9K4E limits system pressure between 4 and 210 bar while passing up to 450 l/min. It is pilot-operated, uses a poppet seat design and mounts on an ISO 6264-08-13 subplate. Maximum operating pressure is 350 bar.
Benefits
- Setting range 4 to 210 bar, suited to accumulator and clamping circuits of that rating
- 450 l/min flow in size 25 at a maximum operating pressure of 350 bar
- Poppet seat design with low leakage, so holding phases run longer between top-ups
- Solenoid unloading on 24 VDC through a 3-pole connector (2 + PE)
- Internal hexagon under a protective cap, NBR seals, 5.36 kg

Application
The valve protects power units that charge accumulators or hold clamping forces. Low leakage across the poppet seat stretches the interval between two recharge cycles. Electrical unloading lets the pump keep running without building pressure during the holding phase.
