Product Overview
In aviation hydraulic systems, relief valves are used to limit the system's maximum pressure, absorb pressure peaks, and protect critical components.
Our 2.5mm cartridge relief valve is specifically designed for aviation hydraulic applications. Its cartridge design provides high opening pressure, stable discharge capacity, and wide temperature range adaptability, making it suitable for integration into valve blocks or hydraulic modules.
