Types and Features of Natural Gas Ball Valves
Understanding the distinctions between ball valve types is essential for selecting the right valve in natural gas applications:
Floating Ball Valves: The ball is not fixed but floats within the valve body, pushed against the downstream seat by differential pressure to ensure tight sealing. They are cost-effective and commonly used for small to medium diameters and moderate pressures.
Trunnion Mounted Ball Valves: These feature shaft supports at the top and bottom of the ball, reducing actuation torque and enabling use in larger diameters or higher pressure systems. Their design also improves seat sealing and valve stability under fluctuating process conditions.
Top-Entry Ball Valves: Designed for in-line service and maintenance, the valve bonnet allows the internal components to be accessed without removing the valve body from the pipeline, minimizing process disruption.
Metal-Seated Ball Valves: Suitable for harsh process conditions such as sour gas or highly abrasive flows, these valves use hardened metal seats instead of soft seals to resist wear and corrosion.
V-Type Ball Valves: Designed for precise flow control, the V-shaped seats provide self-cleaning and enhanced shut-off capability, useful for regulating natural gas flow in processing units.
Each valve type incorporates rigorous design features including fire-safe certifications, anti-static mechanisms to prevent ignition, blowout-proof stems, and compliance with environmental and safety standards.
