Pressure Relief Valve DBG20-1X/200E1 - Bosch Rexroth R900512481

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.
