At 400 l/min pump delivery the relief valve has to carry the full flow without letting pressure run away. The DBW20B2-5X/200 does exactly that across a setting range of 4 to 200 bar and weighs 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.
