Three way flange ball valves and gate valves are both types of valves, but their difference is that ball valves use a ball that rotates on their central axis to open and close. Ball valves are mainly used in pipelines to cut off, distribute, and redirect the flow of media.
● Reasonable Design: The structure is compact, effectively reducing installation space and allowing the valve to be flexibly used in various pipeline systems.
● Corrosion Resistance: This valve is made of high-quality materials, which have excellent wear resistance and a long service life.
● Flange Connection: This connection method ensures a tight fit between the valve and the pipeline, reduces the possibility 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.
