The Hydac DB4F-012-350V is a high-performance, pilot-operated pressure relief valve designed as a screw-in cartridge. It plays a crucial role in safeguarding hydraulic systems by limiting the system pressure to a pre-adjusted maximum value. When the pressure exceeds the set point, the valve opens to divert excess flow to the tank, preventing damage to system components. Featuring robust construction and FKM (Viton) seals, the DB4F-012-350V ensures reliable performance and excellent fluid compatibility across a wide range of industrial and mobile hydraulic applications.
