About Af Hydro Cast Iron Butterfly Valve, 5" ANSI

Butterfly valves are quarter-turn rotational motion valves used in pipelines to control the flow of fluids or gases. They have a simple and fast operation, requiring a 90° rotation to fully open or close the valve. The main difference of butterfly valves compared to other valves is the disc, which remains in the flow and causes a pressure change regardless of the valve's position. There are different types of butterfly valves, including wafer and lug types, each suitable for specific applications. The valve achieves flow stoppage by sealing the disk against a seat in the valve body, either using an elastomeric seat or a seal ring arrangement. Butterfly valves have advantages such as low weight, compact design, and low maintenance costs, making them suitable for large flow applications at relatively low pressure or handling slurries. They are used in various industries, including food processing, refineries, and shipbuilding. Butterfly valves offer advantages such as quick operation, availability in large sizes, and low-pressure drop, but they have limitations in throttling services with low differential pressure and can be affected by cavitation and choked flow. Proper installation involves ensuring clean surfaces, aligning the pipe-work, and gradually closing and opening the valve to check for proper clearances. The material used for constructing this Wafer Type Butterfly Valve is Cast Iron that have a high strength, excellent wear resistance, and good heat retention properties. The maximum working pressure is up to 150 PSI and a temperature range of -30°C to 120°C. There are 2 ANSI 150# connection.
