How does the fire safe double offset high performance butterfly valve works?

Mar 27,2023

The fire safe double offset high performance butterfly valve works by controlling the flow of fluid or gas through a pipe or duct. The valve is composed of several key components, including a disc, stem, actuator, and body.

The disc, which is located in the center of the valve, is connected to the stem and is responsible for regulating the flow of fluid or gas. The stem, in turn, is connected to an actuator, which can be either manual or automated. The actuator is responsible for moving the stem and disc to open or close the valve.


When the valve is in the closed position, the disc is rotated perpendicular to the direction of flow, creating a tight seal that prevents fluid or gas from passing through. When the valve is opened, the disc is rotated parallel to the direction of flow, allowing fluid or gas to pass through the valve and into the pipe or duct.


The double offset design of the valve provides several benefits. First, it reduces the amount of friction and wear on the valve components, allowing for smoother operation and a longer service life. Second, it enables a tighter seal to be maintained, even under high pressure conditions. This helps to prevent leaks and reduce the risk of damage to surrounding equipment.


In the event of a fire, the fire safe features of the valve are activated. For example, fire-resistant seals and packing materials help prevent leakage and maintain function in high-temperature environments. Additionally, the valve may be designed to automatically shut off to prevent the spread of flames and minimize damage. Overall, the fire safe double offset high performance butterfly valve is a reliable and durable option for controlling the flow of fluids and gases in industrial applications.



FEIDA VALVE also build up a dustless workshop to produce ultra-clean valve for some critical working condition such as nuclear industry, semiconductor industry etc.


In the dustless workshop, FEIDA also produce the food-grade valves. FEIDA food-grade valve is certificated by Food and Drug Administration United States (FDA).
