Pressure Relief Valve DBW20B2-5X/200-6EG24N9K4E - Bosch Rexroth R900783560

The DBW20B2-5X/200-6EG24N9K4E carries 400 l/min and limits system pressure to a setting between 4 and 200 bar. It is pilot-operated in poppet seat design, mounts on an ISO 6264-08-13 subplate and is unloaded by a 24 VDC solenoid.

Benefits

• 400 l/min relief capacity, matched to pumps of that delivery range
• Setting range 4 to 200 bar, maximum operating pressure 350 bar
• Poppet seat design, which keeps leakage low while closed
• Subplate mounting to ISO 6264-08-13, 2 ports, size 25
• Internal hexagon under a protective cap, NBR seals, 5.34 kg

Application

The valve acts as pump protection in power units delivering around 400 l/min, for example on presses and test benches. The poppet seat keeps the circuit tight until the setting is reached, which limits leakage losses. Once it opens, pressure drops back to the set value at once.
