Here's a comprehensive description of air valves:

1. Functionality:

   • Air valves are designed to release or expel trapped air or gas from piping systems, allowing the efficient flow of liquid (e.g., water, sewage, or other fluids) without air-related issues.

2. Operating Principle:

   • Air valves operate based on simple mechanical principles. When air accumulates in a pipeline due to the upward flow of fluid, the air valve automatically opens to release the trapped air, allowing it to escape from the system.

3. Types of Air Valves:

   • There are several types of air valves designed for specific applications and operating conditions:
     • Air Release Valves (ARVs): These valves are typically installed at high points in the pipeline to release air during system filling or operation.
     • Air Vacuum Valves (AVVs): AVVs are installed at high points and near pumps to prevent the formation of vacuum conditions by admitting air into the system when necessary.
     • Combination Air Valves: These valves combine the functions of air release and vacuum release into a single unit, providing comprehensive air management capabilities.

4. Construction and Design:

   • Air valves are typically constructed from durable materials such as ductile iron, stainless steel, or thermoplastics, depending on the application and environmental conditions.
   • They consist of a body housing the valve mechanism, an air release orifice, a float or diaphragm mechanism to control valve operation, and sealing elements to prevent leakage.

5. Operating Mechanism:

   • Air valves may utilize various operating mechanisms, including float-operated, diaphragm-operated, or combination mechanisms, to control the opening and closing of the valve based on the presence or absence of air.

• The Single Disc Check Valve (Wafer Type Single Disc Check Valve) consists of four main components, the body, a disc, a star guide and a spring. The Disc check valves are opened by the pressure of fluid and closed through compression spring as soon as flow stops thus preventing reverse flow.
