Features of dome valve:

① Unhindered material flow throughout the chamber

②. Simple and reliable design

③. Flexible opening and closing, can shut down dynamic and static material columns

④. Complete specifications and sizes: dome valve DN50, dome valve DN80, dome valve N100, dome valve DN125, dome valve DN150, dome valve DN175, dome valve DN200, dome valve DN250, dome valve DN300

⑤. A strong pressure seal can be formed when closed

⑥, can withstand temperatures from -20℃ to 480℃

⑦. Long service life and low maintenance

⑧. The material conveying system of the power plant operates normally, and the service life of the plug-in seal ring is more than one year

Dome valve principle:

①. The exhaust dome valve can cut off the flowing material flow or static material column entering the pressure tank, and then close to achieve sealing. This ensures that the filling rate in the tank is 100%, and there is no need to rely on the level meter of the sending tank, so the control principle is simple and reliable.

② When handling abrasive materials, the expandable pressure seal ring embedded in the dome valve seat ensures the working pressure difference before and after the valve. The elastic expandable seal ring can be sunken into the material particles, avoiding the sliding of the material particles due to the pressure difference and the wear of the valve seat and seal ring.

③ When slurry, bulk powder, particles, lumps or dust filled with gas will wear the seal ring, resulting in ineffective sealing. The expandable seal ring provides continuous wear compensation. The pressure difference will accelerate the wear of the traditional hard seal valve, and the expandable seal ring provides continuous wear compensation.

④. Thermal expansion will hinder the continuous operation of the dome valve; the expandable sealing ring can provide wear compensation in the temperature range of -40℃ to 320℃; the specially constructed dome valve can perform work above this temperature range.

⑤ The displacement of the rotating dome valve core in the valve body enables the dense material column to rotate, so that the dome valve completely filled with material can pass through the filled material to close and seal.
