Floating Ball Valves

What Are Floating Ball Valves?
A floating ball valve uses a ball that is not supported by trunnion bearings. Under line pressure, the ball is pressed against the downstream seat, creating the seal. The ball “floats” between the upstream and downstream seats, and the sealing force increases with line pressure. This design is well suited for smaller to medium sizes and moderate pressure classes where the operating torque remains manageable.
Honiks is a factory-backed industrial valve supplier in China with access to qualified partner factories for floating ball valve production. See HN105 Floating Ball Valve for catalog reference data covering Class 150-600 configurations.

Frequently Asked Questions
What size range is available for floating ball valves?
The catalog reference covers smaller to medium sizes. For specific size availability by pressure class and end connection, contact Honiks with your project requirements.
Can floating ball valves be used for higher pressure classes?
Floating ball valves are commonly used in moderate pressure classes. For higher pressure classes, a fixed ball design may be more suitable. Contact Honiks to discuss the right valve configuration for your operating conditions.
