Dual-Ball Design: Adopts two balls and two valve seats to achieve dual isolation function. Even if one sealing surface fails, the other can still maintain sealing, ensuring no medium leakage.
Floating Ball Structure: The ball can float freely under the pressure of the medium, fitting tightly with the valve seat to form an excellent sealing effect. It also has an automatic pressure relief function: when the pressure in the valve cavity is too high, pressure can be automatically relieved through the valve seat to prevent valve body rupture.
Butt-Welded Connection: The valve body is connected to the pipeline via butt welding. This connection method features high strength and good sealing performance, capable of withstanding high pressure and temperature, suitable for various harsh working environments, and facilitating pipeline installation and maintenance.
Fire and Anti-Static Design: In case of fire, even if the sealing ring is burned, the metal components of the ball valve can still form a metal-to-metal hard sealing structure to prevent medium leakage and fire spread. Meanwhile, the conductive device inside the ball valve can conduct static electricity into the ground, avoiding safety accidents caused by static electricity.
Multiple Sealing Forms: Offers both soft sealing and hard sealing options. Soft sealing uses high-performance polymer materials such as PTFE and PEEK, with excellent sealing performance and corrosion resistance; hard sealing adopts a metal-to-metal sealing method, suitable for high-temperature, high-pressure, and high-wear working conditions.
Emergency Greasing Function: Greasing ports are provided at the valve seat and stem. When the sealing surface is damaged, sealing grease can be injected through the greasing device to achieve emergency sealing, extend the service life of the valve, and ensure the normal operation of the system.
