2024 Guide to 100mm Gate Valve Selection

1. What is a 100mm gate valve?

   A 100mm gate valve is a type of valve used to control the flow of liquids or gases in pipelines. The "100mm" refers to the nominal diameter of the valve, indicating that it has a bore size of 100 millimeters. Gate valves are designed to be fully opened or closed, allowing for minimal resistance to flow when fully open.

2. What are the main applications of 100mm gate valves?

   These valves are commonly used in various industries, including water supply systems, wastewater management, oil and gas pipelines, and chemical processing. They are ideal for applications that require a minimal pressure drop and full flow capability.

3. How do you select a suitable 100mm gate valve?

   When selecting a 100mm gate valve, consider the following factors:

   • Material: Choose a valve material compatible with the fluid being handled. Common materials include brass, stainless steel, and cast iron.
   • Pressure Rating: Ensure the valve can withstand the maximum pressure of the system. Check the class rating, such as ANSI Class 150 or Class 300.
   • Temperature Range: Verify that the valve can operate within the temperature limits of your application.
   • Type of Operation: Decide between manual or automated operation, depending on your needs.
   • End Connections: Choose the appropriate connection type for your piping, such as flanged or threaded ends.
4. What maintenance is required for 100mm gate valves?

   Regular maintenance is essential for ensuring the longevity and efficiency of gate valves. Key maintenance tasks include:

   • Inspecting for leaks, corrosion, or flow obstruction.
   • Operating the valve periodically to prevent seizing.
   • Lubricating any moving parts, if applicable.
   • Replacing seals or gaskets as needed to maintain a tight closure.
5. What are the advantages of using a 100mm gate valve?

   The advantages of using a 100mm gate valve include:

   • Minimal flow resistance when fully open.
   • Good sealing capability when closed, preventing leaks.
   • Simple design, making it easy to operate and maintain.
   • Versatility in various applications and industries.
