Xiangyu Product Page

Purchasing a 2 Piece Trunnion Mounted Ball Valve is a critical investment for any industry or commercial facility. These valves are designed to control the flow of fluids in pipelines and are commonly used in various applications such as petrochemical, oil & gas, food & beverage, pharmaceutical and other industries. The valves' design and construction affect their performance, reliability, and lifetime cost-effectiveness. When purchasing a 2 Piece Trunnion Mounted Ball Valve, some crucial inquiries need to be made to ensure that the valve meets your requirements.

Here are some of the essential inquiries to make:

1. What is the valve's material and construction?

The valve's material and construction must be able to withstand the fluid's properties, temperature, pressure, and other environmental factors. Common materials used for 2 Piece Trunnion Mounted Ball Valves are carbon steel, stainless steel, and alloy steel. The valve's construction is typically a two-piece design for easier maintenance, and the ball-trunnion is either floating or fixed, depending on the application's requirement.

2. What are the valve's end connections?

The valve's end connections must match the pipeline's size and material to ensure proper installation and function. Common end connections include flanged, threaded, and butt-welded connections, depending on the piping system's requirements and standards.

3. What is the valve's pressure rating?

The valve's pressure rating determines its working pressure and the maximum pressure it can withstand without failure. The pressure rating is typically indicated in pounds per square inch (psi), and the valve must be rated higher than the maximum operating pressure of the piping system. It is essential to determine the valve's pressure rating to ensure that it is compatible with the piping system's pressure requirements.

4. What is the valve's bore size?

The valve's bore size determines the flow capacity of the valve and must match the piping system's flow requirements. The bore size is the inside diameter of the valve's ball, and it is typically measured in inches or millimeters.

5. What is the valve's temperature rating?

The valve's temperature rating determines the maximum and minimum temperature that it can handle without affecting its performance or causing failure. The temperature rating is typically indicated in degrees Fahrenheit or Celsius. The valve's material and construction also contribute to its temperature rating, and it is essential to consider the temperature requirements of the piping system before selecting the valve.

6. What is the valve's sealing mechanism?

The valve's sealing mechanism plays a critical role in its performance, reliability, and maintenance. Common sealing mechanisms include soft-seated and metal-seated options, depending on the application's requirements. Soft-seated valves provide better sealing performance but require regular maintenance, while metal-seated valves offer durability and extended service life but may not provide the same level of sealing performance as a soft-seated valve.

7. What are the valve's testing and certification standards?

The valve's testing and certification standards ensure that it meets the required quality, safety, and environmental standards. Common standards include API, ASME, ISO, and ANSI, depending on the industry's requirements. The valve must undergo rigorous testing before being certified, and it is essential to verify the valve's testing and certification standards before purchasing.

Conclusion:

Purchasing a 2 Piece Trunnion Mounted Ball Valve involves critical inquiries to ensure that the valve meets your application's requirements. The valve's material and construction, end connections, pressure rating, bore size, temperature rating, sealing mechanism, and testing and certification standards must be considered. Making informed decisions based on these inquiries will ensure that the valve performs reliably and cost-effectively over its service life.
