Pressure Relief Valve DBG20-1X/315YP2 - Bosch Rexroth R901143750

On the DBG20-1X/315YP2 the 315 bar rating covers the entire permitted operating pressure, so a second valve for the upper range is not needed. The valve is pilot-operated, works as a seat valve and follows the command value of the external digital electronics up to a flow of 600 l/min.

Key benefits

• Pressure rating 315 bar, equal to the maximum operating pressure, the command range is fully used.
• Flow up to 600 l/min in size 20.
• ISO 6264-AS-08-2-A interface, for subplate mounting, threaded connection or block installation.
• Seat valve design with low leakage in the closed position.
• Symbol A to B and A to Y, venting through the Y port is possible.
• NBR seals, HL hydraulic fluid, 6-pole mating connector (5 + PE) to DIN 43651.

Applications

A typical use is as the pressure setting element in presses and test rigs working close to the permitted maximum. The digital electronics sit outside the valve, so they can be replaced without opening the hydraulic circuit. With two switching positions and four ports the valve can both control pressure and vent the circuit. It weighs 8.1 kg.
