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.

SND Foundry have been specializing in the production and sales of manhole cover and gully grating, valves, pipe & pipe fitings and metal castings products nearly 20 years.
