The Top mounted end of line relief valve is a valve that is installed at the end of a piping system or at a specific location to automatically open when the pressure exceeds a set point to release pressure and protect the system from damage that can result from excessive pressure.
The working principle of top-mounted terminal drain valves is usually based on a balance between spring force and medium pressure. There is a spring inside the valve whose preload force sets the opening pressure of the valve. When the pressure inside the system rises and exceeds the preload force of the spring, the valve will overcome the resistance of the spring and open, allowing the medium to pass through and release the pressure. Once the system pressure drops below the set value, the spring closes the valve, preventing further media discharge.
Top mounted end of line relief valve Characteristics and advantages:
Automatic control: Without manual intervention, it can automatically open and close when the pressure exceeds the set value.
Protection system: effectively prevent system damage due to overpressure, protect the safety of equipment and personnel.
Adjustable: Different opening pressures can usually be set by adjusting the preload force of the spring to adapt to different system requirements.
Durability: Made of corrosion-resistant and heat-resistant materials, it can be used in harsh working environments for a long time.
