Maintenance And Repair Tips of Butterfly Valve

A butterfly valve, an integral component in fluid flow regulation, operates through a rotating disk to manage liquid flow within a process. Positioned vertically, the valve features a metal-based disc that facilitates fluid closure, akin to the operation of a ball valve. In comparison to its counterparts, the butterfly valve boasts several advantages:

Lightweight Construction: The valve's lightweight nature reduces the need for extensive support structures.

Cost-Effectiveness: Relative to other valves with differing designs, the butterfly valve offers a more economical solution.

Widely utilized in industries such as food and shipbuilding, the butterfly valve serves as a reliable and efficient two-way valve. Its installation proves cost-effective, especially when compared to other valve types. By closing the disc, the butterfly valve adeptly guides and halts the flow of liquid or gas.

Maintenance and Repair Tips for Butterfly Valves in Diverse Pipelines:

Routine Maintenance: Butterfly valves require regular upkeep, with maintenance categorized into minor, medium, and heavy repairs based on working environments. The specifics depend on pipeline conditions, varying across industries.

ㆍMinor Repairs: Scheduled maintenance involves tasks like cleaning nozzles and oil cups, replacing O-rings, cleaning threads and valve stems, removing debris, tightening screws, and configuring handwheels.

ㆍMedium Repairs: This level of maintenance, suitable for factory overhauls, encompasses minor repair elements and adds tasks such as part replacements, valve body repairs, sanding of seals, and straightening valve stems.

ㆍHeavy Repairs: Reserved for extensive damage, heavy repairs include all mid-repair tasks, along with valve stem replacements, bracket repairs, and the replacement of springs and seals.

In order to prevent corrosion and ensure proper functioning, butterfly valves should undergo meticulous maintenance. Some key practices include:

ㆍLubrication: Apply grease regularly to the valve's neck through the lubricating oil fitting. Ensure consistent greasing intervals to prevent rust.

ㆍGearbox Maintenance: Use lithium-based grease for gearbox upkeep to enhance longevity and smooth operation.

ㆍCleaning: Employ any silicon-based product or lubricant to clean all valve parts efficiently.

ㆍRotation: For infrequently used valves, rotate or cycle them at least once a month to prevent stiffness and ensure readiness for operation.
