Q41F Gas floating ball valve
The Q41F Gas Floating Ball Valve is a high-performance floating ball valve specifically designed for natural gas, liquefied petroleum gas (LPG), coal gas, biogas, and other gaseous media transmission systems. The valve adopts a precision-machined floating ball structure, utilizing medium pressure to push the ball against the downstream seat, ensuring reliable sealing performance and low operating torque.
Designed in accordance with international standards, the valve offers excellent sealing capability, fire-safe protection, anti-static design, and blowout-proof stem construction. It is widely used in gas transmission pipelines, city gas distribution networks, petrochemical plants, oil & gas facilities, power plants, and industrial utility systems.
With robust construction and superior safety performance, the Q41F Gas Floating Ball Valve provides reliable shut-off and long-term service under demanding operating conditions.
