The Bucher DDRRZ-7020-4-H-2 is a proportional 3-way pressure-reducing cartridge designed to regulate hydraulic system pressure by maintaining a user-set downstream value up to 20 bar. It serves in hydraulic circuits where stable, adjustable downstream pressure protects components, supports consistent actuator performance, and helps manage load pressure in the system. As a Bucher Hydraulics component, this cartridge embodies compact cartridge-based pressure control with proportional response, delivering controlled reduced pressure to the downstream port while limiting the input pressure to the programmed setting.
