A circuit passing 600 l/min needs a relief valve whose set point follows an electrical command instead of a spring screw. The DBG20-1X/200E1 is built for the 200 bar rating, withstands 315 bar and works as a pilot-operated seat valve, symbol A to B.

A pressure relief valve protects the circuit when the actuator stalls. The DBG20-1X/200E1 does not cap pressure at one fixed setting, it tracks the electrical command value instead, and it does so at flows up to 600 l/min in size 20.
Benefits
- Up to 600 l/min flow in size 20, maximum operating pressure 315 bar.
- Pressure rating 200 in the type code, matched to circuits working around 200 bar.
- Pilot-operated seat valve, tight shut-off at rest, symbol A to B.
- Digital external electronics, 24 V DC, the command value comes from the machine control.
- Three mounting options, subplate, threaded connection and block installation.
- 8.16 kg with NBR seals, connection diagram ISO 6264-AS-08-2-A.

Applications
Presses and large cylinders whose system pressure is switched several times per cycle are the typical case. As a seat valve it closes with low leakage at rest, which matters during long holding phases. The 6-pole (5 + PE) mating connector to DIN 43651 carries the link to the electronics.
Manufacturer
Bosch Rexroth, material number R900512481, product family DBG. The matching digital amplifier electronics are ordered separately, the valve itself carries no control card.
