Key Features:

1. Brass Construction:

   • Made from brass, which provides excellent corrosion resistance, durability, and suitability for water, air, and non-aggressive fluids.

   • Ideal for residential, commercial, and light industrial applications.

2. Threaded Ends:

   • Features NPT or BSPT threaded ends for easy installation in threaded piping systems.

   • Eliminates the need for flanges or welding, making it a cost-effective and space-saving solution.

3. Swing Mechanism:

   • Utilizes 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.

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, compressed air systems, and irrigation systems.

   • 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 connections.

   • Compact and lightweight design.

   • Cost-effective solution for flow control.
