MAIN FEATURES
DBB Ball Valve
Duplex structure design: DBB ball valve adopts duplex structure design, the valve body consists of two spheres, each of which controls one way fluid passage. This design makes the valve more flexible and reliable in controlling the fluid, able to open or close the two spheres at the same time, thus realizing the precise control of the two fluid paths12.
Excellent sealing performance: DBB ball valves use seals made of high-performance materials with excellent sealing performance, which can effectively prevent fluid leakage and ensure the stability and safety of the fluid control system1.
Fire-resistant structure: DBB ball valves are equipped with a fire-resistant structure, when the seal ring burns out, the various sealing parts of the ball valve can form a metal-to-metal hard sealing structure, which effectively prevents the spread of the medium and prevents the fire from expanding45.
With lock structure: for installation in the field or need to prevent misoperation of non-staff occasions, DBB ball valves are equipped with locking holes in the fully open or fully closed position, which can be locked and play the role of safety insurance23.
Anti-static structure: in the ball and stem, stem and valve body between the conductive spring, to ensure that the valve in the opening process of static electricity can be set up through the static channel into the pipeline into the ground, to avoid static ignition ignition flammable media, to ensure system safety 23.
Blocking and discharging function: DBB duplex ball valves not only have the fluid control function of conventional ball valves, but also have the function of blocking and discharging. This further enhances the safety and reliability of the valve, especially when it is necessary to quickly cut off the fluid path or discharge the residual fluid in the pipeline, the performance is particularly good.
Easy to operate: DBB ball valves are characterized by simple structure and easy operation, which can quickly realize the opening, closing and adjustment of the fluid. Its structural design makes the maintenance process relatively simple, easy to check and replace parts, reducing maintenance costs and time.
