BQ41F is a special type of insulated ball valve, which belongs to the same category as flange gate valves. Its uniqueness lies in its closing mechanism, which promotes opening and closing by rotating a ball around the centerline of the valve body. Ball valves are mainly used for isolating, distributing, and changing the direction of medium flow in pipelines. In recent years, two-piece and three piece ball valves have been widely adopted as innovative products. These valves are usually installed horizontally inside the pipeline.
● High Thermal Insulation Performance: Its unique integrated insulation sleeve design effectively reduces heat loss during medium transmission, thereby improving energy utilization efficiency. It is particularly suitable for applications that require maintaining medium temperature.
● Easy Installation: The integrated design minimizes the number of connectors, making the overall structure more streamlined. This not only reduces the required installation space, but also simplifies the installation process and lowers installation costs.
● Reliable Sealing Performance: The sealing surface of float valves is usually made of high-quality materials and precision machining to ensure effective sealing when the valve is closed, prevent medium leakage, and thus improve 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.
