BQ41F is a specialized type of insulated ball valve, falling within the same category as flanged gate valves. Its unique feature is its closing mechanism, which involves a ball rotating around the centerline of the valve body to open and close. Ball valves are primarily used to cut off, distribute, and change the direction of media flow within pipelines. In recent years, double-piece and triple-piece ball valves have been widely adopted as innovative products. These valves are typically installed horizontally within the pipeline.
● High Thermal Insulation Performance: Its unique integrated thermal insulation sleeve design effectively reduces heat loss of the medium during transmission, thereby enhancing energy utilization efficiency. It is particularly suitable for applications requiring the maintenance of medium temperature.
● Easy Installation: The integrated design minimizes the number of connectors, resulting in a more streamlined overall structure. This not only reduces the installation space required but also simplifies the installation process and decreases installation costs.
● Reliable Sealing Performance: The sealing surface of the float valve is typically constructed from high-quality materials and precision processing to ensure effective sealing when the valve is closed, preventing medium leakage and thereby improving system safety.

Q1:What is the benefit of the floating ball design?
The floating ball design allows for smooth, efficient flow control as the ball moves with the flow of the fluid, ensuring minimal resistance and optimal performance.
Q2:What is the valve's temperature and pressure range?
The valve can handle temperatures from -40ºC to 300ºC (hard seal) or -40ºC to 180ºC (soft seal) and is rated for nominal pressures from PN1.6 to 6.4 MPa.
