Here are the top 10 problems that are commonly associated with concentric disc butterfly valves:

Leakage: One of the most common problems with butterfly valves is leakage, which can occur due to a variety of reasons including worn-out seats, loose connections, or damaged seals.

Sticking: The valve disc may become stuck in the open or closed position due to corrosion, buildup of debris, or problems with the actuator.

Corrosion: Corrosion can occur due to the presence of moisture, harsh chemicals, or abrasive materials in the fluid being transported.

Wear and Tear: Over time, the valve components can become worn out due to repeated use, leading to problems such as leakage or sticking.

Abrasion: The disc and seat of the valve may become damaged due to abrasive particles in the fluid, leading to leakage or reduced flow.

Misalignment: The valve may become misaligned due to improper installation or damage during transportation, concentric disc butterfly valve leading to problems with the sealing or opening and closing of the valve.

Actuator failure: The actuator is the component that opens and closes the valve, and problems with this component can lead to problems with the valve’s operation.

Clogging: The valve may become clogged due to buildup of debris, leading to reduced flow or complete blockage.

Stiff Operation: The valve may become difficult to operate due to corrosion or buildup of debris on the components, leading to increased effort required to open and close the valve.

Overloading: Overloading the valve by exceeding its maximum pressure rating can lead to problems with the sealing, disc, or actuator, and may result in damage to the valve.
