American Standard Ball Valve Overview
The American standard ball valve is a versatile valve designed for cutting off, distributing, and redirecting pipeline flow. Unlike flange gate valves, its closure mechanism is a rotating sphere, making it highly efficient and reliable. These valves are typically installed horizontally and come in two-piece and three-piece designs, widely used across various industries.

Types of Ball Valves

Floating Ball Valve
The ball floats under medium pressure, pressing against the sealing surface to ensure a tight seal. This design is simple, offers excellent sealing performance, and is ideal for medium and low-pressure applications.

Fixed Ball Valve
The ball remains stationary under pressure, while the valve seat adjusts to maintain a secure seal. Equipped with bearings for reduced torque, this type is perfect for high-pressure and large-diameter systems.

Elastic Ball Valve
With an elastic ball and metal sealing components, this valve is built for high-temperature and high-pressure environments. External force ensures reliable sealing when medium pressure alone is insufficient.
