Three piece flange ball valve is a sphere, which rotates around the center line of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute and change the direction of the flow of media.
● Reasonable Design: Compact structure, effectively reduce the installation space, so that the valve can be flexibly used in a variety of pipeline systems.
● Corrosion Resistance: The valve is made of high quality materials, with good wear resistance and long service life.
● Welding Connection: This connection method makes the valve and pipeline connection firm, not easy to leak, improve 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.
