AWWA stands for American Water Works Association which is a standard that is given to the valves. These valves are typically used to regulate water flow in underground pipelines. This type of valve is specifically designed for heavy pressure service. Within a framework, Awwa valves control the flow and pressure of fluids, gases, and slurries. Controllers are another name for them, and they're used in a variety of applications. Valves differ in length, form, capability, and function. Valve characterization can be done in a number of ways, including using the control part and the valve work.
