How to Select the Right Ball Valve
Choosing the correct ball valve depends on your application parameters. Here are the key factors to evaluate.
Media Type
Consider whether the fluid is corrosive, abrasive, or cryogenic — this determines body and seal material selection.
Pressure & Temperature
Match the valve pressure class and material grade to your operating conditions and ASME B16.34 limits.
Mounting Type
Floating ball valves suit smaller sizes; trunnion-mounted designs are preferred for large-diameter, high-pressure applications.
Actuation Needs
Manual lever, gearbox, pneumatic, electric, or hydraulic — choose based on frequency of operation and automation requirements.
