Overview
A butterfly valve is a quarter-turn rotational shut-off device designed to regulate or isolate fluid flow within industrial piping systems. Typically manufactured from cast iron, stainless steel, or carbon steel, these units adhere to international standards such as ANSI and API for disc geometry and sealing performance.
Application
- Water Treatment: Managing raw water intake and distribution networks.
- Petrochemical: Controlling hydrocarbon flows in refineries and processing plants.
- HVAC Systems: Regulating chilled and hot water circulation in commercial buildings.
- Power Generation: Isolating cooling water circuits in thermal and nuclear facilities.
Precautions
- Seal Inspection: Conduct periodic checks on rubber or PTFE seats to prevent leakage.
- Lubrication: Ensure stem and bearing mechanisms are regularly greased to avoid seizing.
- Pressure Limits: Strictly operate within rated pressure and temperature boundaries.
- Replacement Cycle: Replace worn discs or seals immediately upon detecting erosion or deformation.
