Introduction
When selecting a ball valve for industrial applications, several factors need to be considered to ensure optimal performance and longevity. This guide covers the key aspects of ball valve selection.
1. Material Selection
The material of the valve body and ball is critical. Common options include:
- Carbon steel (ASTM A216)
- Stainless steel 304/316
- Duplex and super duplex stainless steels
- Alloy materials for corrosive environments
2. Pressure Rating
Ball valves are typically rated according to ANSI or API standards. Common pressure classes include 150, 300, 600, 900, 1500, and 2500.
3. End Connections
Choose from threaded, flanged, welded, or wafer connections based on your piping system requirements.
