Working Temperture: -20~425℃
Material: WCB/CF8/CF8M/CF3/CF3M
Design&Manufacture: ASME B 16.34

Key Features:

1. Vertical Installation:

   • Specifically designed for vertical flow applications, where gravity assists in the valve's operation.

   • Ensures proper sealing and prevents backflow in upward or downward flow configurations.

2. 2-Piece Design:

   • Consists of two main parts: the body and the bonnet, which are threaded together.

   • Allows for easy disassembly, maintenance, and cleaning.

3. Threaded Connections:

   • Features male or female threaded ends (NPT, BSP, etc.) for simple installation in threaded piping systems.

   • Eliminates the need for welding or flanges, making it ideal for smaller systems.

4. Material:

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

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

5. Operation:

   • Utilizes a spring-loaded disc, ball, or swing mechanism to allow forward flow and automatically close to prevent backflow.

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

6. Applications:

   • Commonly used in water supply systems, HVAC systems, fuel lines, compressed air systems, and chemical processing.

   • Suitable for low to medium-pressure systems.

7. Advantages:

   • Easy to install and maintain.

   • Compact and lightweight design.

   • Reliable performance in vertical flow applications.

   • Cost-effective solution for preventing backflow.
