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.
Our high-temperature ball valves are manufactured using advanced materials and complex processes, ensuring excellent heat resistance and extended service life. They are compact in design, easy to install, and save a significant amount of space, reducing time costs. Each product undergoes comprehensive quality testing to meet industry standards, ensuring trouble-free use. We offer comprehensive after-sales service, including technical consultation and repair services, quickly addressing your needs.
