Total price
A power unit that has to idle without pressure between two cycles needs a valve able to send the full pump flow back to tank on command. The DBW52 in size 52 limits pressure across a range of 3.9 to 180 bar and unloads up to 1500 l/min through its built-on directional spool valve.
Benefits
- Solenoid unloading puts the power unit into pressureless circulation, driven with 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803.
- Rated flow of 1500 l/min matches pump units in the upper power class.
- Adjustment range of 3.9 to 180 bar at a permissible operating pressure of 315 bar.
- Poppet seat main stage keeps leakage low even during long holding phases.
- Internal hexagon with a protective cap secures the setting against accidental turning.
- Flange connection in size 52, CE conformity, mass 28.9 kg.
