Three piece internal thread welded ball valve consists of a sphere that rotates around the centerline of the valve body to achieve opening and closing. This type of ball valve is mainly used in pipeline systems to cut off, distribute and change the direction of the medium flow.
● Reasonable Design: The compact structure effectively reduces installation space, allowing the valve to be flexibly applied to various pipeline systems.
● Corrosion Resistance: This valve is constructed from high-quality materials, offering excellent wear resistance and an extended service life.
● Welding Connection: This method ensures a secure connection between the valve and the pipeline, reduces the likelihood of leakage, and enhances the sealing and safety of the system.

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.
