Product Description:

A Overflow Valve, also known as a Safety Valve or Relief Valve, is a valve used to control pressure in a fluid system. Its main function is to automatically open and guide excess fluid outflow when the system pressure exceeds the set value to prevent the system from overpressurizing.

Working principle: The relief valve works on the principle of pressure balance. They usually consist of a valve body, a spring, a spool and a regulating device. In normal operation, the force applied by the spring keeps the spool closed and prevents fluid from passing through the valve. When the system pressure exceeds the set pressure value, the pressure will overcome the spring force, causing the spool to open, directing the excess fluid to the low pressure area or back to the tank.

Protection function: The main function of the relief valve is to protect the components in the fluid system from excessive pressure damage. When the system pressure exceeds the set safe pressure, the relief valve opens and guides the excess fluid out to reduce the system pressure and ensure that the system is within a safe range.

Pressure adjustment range: Relief valves usually have an adjustable pressure range. According to the specific application requirements, the opening pressure value of the relief valve can be set according to the system requirements. This makes them suitable for fluid systems with different operating pressure requirements.

Safety and reliability: Safety and reliability are emphasized in the design and manufacturing process of the relief valve. They undergo rigorous testing and quality control to ensure proper operation under a variety of operating conditions and provide reliable overvoltage protection.

Applications: Relief valves are widely used in a variety of hydraulic and pneumatic systems, including industrial machinery, automotive engineering, aerospace, energy and chemical industries. They play a critical safety role in hydraulic systems, preventing damage or accidents due to overpressure.
