What Are The Types Of Fusible Link Safety Shutoff Valves?
- Manual Reset Valves: These valves require manual intervention to reset after the fusible link has melted and the valve has shut off the flow.
- Automatic Reset Valves: Once the fusible link melts and triggers the valve to shut off, these valves automatically reset once the temperature returns to normal.
- Electrically Actuated Valves: These valves incorporate an electrical actuator that responds to the melting of the fusible link, shutting off the flow electronically.
- Mechanical Valves: Mechanical valves rely solely on the physical movement of components, such as springs or levers, triggered by the melting of the fusible link.
- High-Pressure Valves: Specifically designed to withstand and control high-pressure environments, ensuring safety in critical applications.
- Low-Pressure Valves: Tailored for use in low-pressure systems, providing reliable shutoff capabilities in less demanding environments.
What Is Fusible Link Safety Shutoff Valves?
A Fusible Link Safety Shutoff Valve is a crucial safety device designed to automatically stop the flow of gas or liquid when a certain temperature is reached. Utilizing a fusible link mechanism, it melts at a predetermined temperature, triggering the valve to close and prevent potential hazards. These valves are commonly used in applications where fire safety is paramount, such as industrial processes, fuel systems, and automatic fire suppression systems.
How to Select the Right Fusible Link Safety Shutoff Valves?
To select the right Fusible Link Safety Shutoff Valve, consider factors such as the temperature rating, flow capacity, material compatibility, and application requirements. Ensure the valve meets safety standards and is suitable for the specific environment it will be installed in. Additionally, choose reputable brands like Cameron for reliability and performance assurance.
