AWWA valve refers to valves that are designed and manufactured to meet the standards set by the American Water Works Association (AWWA). The AWWA is a non-profit organization that sets standards for the water industry, including the design and construction of valves used in water supply and distribution systems.
AWWA valves are specifically designed to meet the unique requirements of the water industry, such as ensuring clean and safe drinking water, providing reliable and efficient flow control. AWWA valves must meet strict criteria for quality, durability, and performance, as well as adhere to specific standards for materials, coatings, and testing.
PARTS
• Body: The body is the main housing of the valve and contains the internal components.
• Bonnet: The bonnet is a cover that is attached to the body of the valve and provides access to the internal components.
• Disc: The disc is a movable component that controls the flow of fluid through the valve. It can be lifted, rotated or turned to open or close the valve.
• Stem: The stem is a rod that connects the disc to the valve actuator. It moves the disc up and down or rotates it to control the flow of fluid.
• Seat: The seat is a sealing surface that the disc comes in contact with to provide a tight seal and prevent leakage.
• Actuator: The actuator is a mechanism that moves the stem to control the disc and regulate the flow of fluid through the valve. It can be manual or automated depending on the application.
• Gaskets: Gaskets are seals that are placed between the body and bonnet, and between the body and flanges to prevent leakage.
• Bolts and Nuts: Bolts and nuts are used to secure the valve to the pipeline or other components.
• Flanges: Flanges are used to connect the valve to the pipeline or other components.

TYPES
• Double offset butterfly valve: Has a disc that is offset from the centerline of the valve seat and the stem
• Concentric butterfly valve: Has a disc that is centered on the valve seat and stem
