Product Selection Differences for Valve Extension Stems

When selecting valve extension stems, there are several key differences to consider:

1. Material: Valve extension stems can be made of various materials, such as stainless steel, brass, or plastic. The material choice affects the durability and performance of the extension stem.

2. Length: Valve extension stems come in different lengths to accommodate various valve types and applications. It's important to choose the right length to ensure proper valve operation.

3. End Connections: Valve extension stems may have different end connections, such as threaded, flanged, or grooved ends. The end connection should match the valve and piping system for a proper fit.

4. Pressure Rating: Consider the pressure rating of the valve extension stem to ensure it can withstand the operating conditions of the system.

5. Temperature Rating: Similarly, check the temperature rating of the extension stem to ensure it can handle the temperature extremes of the process fluid.

6. Corrosion Resistance: Depending on the application, it's essential to select a valve extension stem with good corrosion resistance to ensure a long service life.

7. Certifications: Look for extension stems that meet industry standards and certifications to ensure quality and compliance with regulations.
