Key Features:

1. Thread/Socket End Connections:

   • Available with threaded (NPT or BSPT) or socket ends for easy installation in threaded or welded piping systems.

   • Eliminates the need for flanges, making it ideal for compact installations.

2. Swing Mechanism:

   • Features a hinged disc that swings open with forward flow and closes with reverse flow.

   • The disc is designed to provide a tight seal when closed, preventing backflow.

3. Material:

   • Constructed from durable materials such as brass, stainless steel, carbon steel, or cast iron, depending on the application and fluid compatibility.

   • Offers resistance to corrosion, high pressure, and temperature.

4. Operation:

   • Works based on pressure differentials: the valve opens when upstream pressure exceeds downstream pressure and closes when the flow reverses.

   • No external actuation is required; the valve operates automatically.

5. Applications:

   • Commonly used in water supply systems, HVAC systems, oil and gas pipelines, chemical processing, and industrial applications.

   • Suitable for both horizontal and vertical (upward flow) installations.

6. Advantages:

   • Provides reliable backflow prevention with minimal maintenance.

   • Easy to install and maintain due to threaded or socket ends.

   • Compact and lightweight design.

   • Cost-effective solution for flow control.
