Key Considerations for Lined Valves

When selecting or buying lined valves, there are several key considerations you should keep in mind. Here are some important factors to consider:

1. Chemical Compatibility: Make sure the lining material used in the valve is compatible with the chemicals and substances it will be handling. Different lining materials such as PTFE, PFA, and FEP have different chemical resistances, so it's crucial to choose the right material for your specific application.

2. Pressure and Temperature Ratings: Ensure that the lined valve can handle the operating pressure and temperature of your system. Check the valve specifications to make sure it is suitable for the conditions in which it will be used.

3. Valve Type and Design: Consider the type of valve (ball valve, butterfly valve, etc.) that best suits your application. Different valve types offer different flow control capabilities and have varying levels of maintenance requirements.

4. End Connection and Size: Choose a valve with the appropriate end connections (flanged, threaded, welded, etc.) and size to fit your piping system.

5. Quality and Reliability: Select valves from reputable manufacturers known for producing high-quality products. This can help ensure the reliability and longevity of the valve in your system.

6. Compliance and Certifications: Check if the lined valve meets industry standards and certifications relevant to your application, such as API, ANSI, or ISO standards.

7. Price and Life Cycle Costs: Consider the initial cost of the valve as well as its maintenance requirements and expected lifespan to calculate the total cost of ownership over the valve's life cycle.

By considering these factors, you can choose the right lined valve for your specific needs and ensure optimal performance in your system.
