BQ41F is a special model of insulated ball valve, which belongs to the same type of valve as flange gate valve. Differently, its closing part is a sphere that rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used to cut off, distribute, and change the flow direction of media in pipelines. Two piece ball valves and three piece ball valves are a new type of valve widely used in recent years. These valves should usually be installed horizontally in pipelines.
● High Thermal Insulation Performance: Its unique integrated insulation sheath design can effectively reduce the heat loss of the medium during transmission, improve energy utilization efficiency, and is particularly suitable for situations where the medium temperature needs to be maintained.
● Easy Installation: Due to the integrated design, the number of connecting components is reduced, making the overall structure more compact. This not only reduces installation space but also simplifies the installation process, reducing installation costs.
● Reliable Sealing Performance: The sealing surface of flange ball valves is usually made of high-quality materials and precision processed to ensure good sealing when the valve is closed, effectively preventing medium leakage and 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.
