A ball valve is a quarter-turn valve designed with a perforated, and pivoting ball to regulate fluid flow. Widely utilized in industrial applications due to their reliability, effortless operation, and versatility, these valves transition seamlessly between open and closed states with a 90° rotation. The center-bored ball design ensures precise alignment with pipeline ports in the open position, enabling unrestricted flow, while the tight shut-off mechanism guarantees zero leakage when fully closed. Ideal for demanding sectors like oil & gas, chemical processing, and water systems, ball valves offer robust performance across diverse pressure and temperature conditions.

A trunnion-mounted ball valve is a quarter-turn valve featuring a perforated ball fixed on a trunnion shaft to regulate fluid flow. These valves provide reduced operating torque and superior long-term performance compared to floating ball designs, making them ideal for high-pressure applications. While their advanced mechanical design ensures reliability in demanding conditions, it also necessitates specialized maintenance protocols. Trunnion-mounted ball valves are widely utilized in critical industries such as oil & gas, LNG, coal gas systems, and high-pressure pipeline networks.

Floating ball valves are a straightforward yet highly effective valve design. They excel in sealing performance compared to trunnion-mounted ball valves, as system pressure directly forces the floating ball against the downstream seat, creating a bubble-tight seal. In contrast, trunnion valves rely on pressure pushing the upstream seat toward the ball, making their sealing performance more susceptible to impurities that may lodge in the seat pocket. This inherent design simplicity ensures floating ball valves deliver consistent reliability in critical applications. They are widely used in oil & gas pipelines, chemical processing, metallurgy, and construction industries, particularly where leak-tight operation is paramount.
