FAQ

Q What is a ball valve used for?

A ball valve is designed for reliable on/off isolation by rotating a ball with a bore through 90 degrees. It is widely used in oil & gas, chemical processing, LNG, water treatment, and industrial pipeline systems requiring tight shutoff.

Q When should I choose a ball valve?

Choose a ball valve when you need bubble-tight sealing, low operating torque, quick quarter-turn operation, and long service life. It is ideal for frequent operation and automated process systems.

Q What is the difference between a floating ball valve and a trunnion-mounted ball valve?

Floating ball valves are suitable for small and medium sizes, while trunnion-mounted ball valves provide lower operating torque and greater stability for high-pressure and large-diameter applications.

Q Can ball valves be used for throttling?

Ball valves are primarily designed for on/off service. Although partial opening is possible, continuous throttling is generally not recommended because it may damage the sealing surfaces.

Q What materials are available for ball valves?

Ball valves are available in carbon steel, stainless steel, duplex stainless steel, alloy steel, and special materials to suit corrosive, high-temperature, cryogenic, and severe-service applications.

Q Which industries commonly use ball valves?

Ball valves are widely used in oil & gas, petrochemical, LNG, chemical processing, power generation, mining, and general industrial applications.
