 Key attribute

Product profile

• Critical Overload Protection As the primary safety device in the hydraulic circuit, these relief valves limit maximum system pressure by diverting excess fluid to the return line when the set value is exceeded. This protects the main pump, hydraulic cylinders, and piping from damage under peak loads. A malfunctioning valve can cause erratic hydraulic functions, a noisy pump, or a system that fails to build adequate pressure.
• Precise Pressure Regulation Manufactured to meet stringent Volvoo standards, these valves ensure precise pressure control and prevent damage from over-pressurization-unlike a worn valve that may stick open or closed. The main relief valve also acts as a buffer during system pressure fluctuations, protecting sensitive components.
