XDV High-temperature butterfly valve products are specially designed high-temperature regulating control valves with reasonable product structure design, easy operation, and reliable use. During operation, it is driven by worm gear, electric or pneumatic actuator to meet the needs of program control and remote control. The high-temperature control butterfly valve system has obtained a national patent. This product has mature technology and advanced structure. It has passed the Zhejiang Provincial New Product Appraisal, and has successively won national key new products, scientific and technological innovation funding projects, and national key Torch Plan projects.

The XDV high-temperature ball valve uses a new sealing material as the valve seat. Compared with hard-sealed ball valves of similar products, the service life can be increased by 3 to 5 times. It has the advantages of stable performance, reliable sealing, low friction, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. Mainly suitable for high-temperature flue gas, engine exhaust, high-temperature mixed gas and other media.

The high-temperature bell valve is a specially designed bell valve in the XDV bell valve series; the product structure is reasonably designed, easy to operate, and reliable to use. The operation can be geared, electric, or pneumatic to meet the needs of program control and remote control. The products are widely used in high-temperature auxiliary lines for sulfur acid production, as well as high-temperature pipelines in smelting and petrochemical systems as control valves.

The angle bell valve is a specially designed angle bell valve in the XDV bell valve series. The product structure is reasonably designed, easy to operate, and reliable to use. The operation can be geared, electric, or pneumatic to meet the needs of program control and remote control. It is widely used in the control, regulation and cutting of flue gas and high-concentration dust gases such as non-ferrous smelting, ferrous smelting, power generation, building materials, light industry and other kilns, reverberatory furnaces, boilers, exhaust gas preheating systems, dust collection systems, etc. Ideal device.

XDV has researched and developed dozens of new XDSs alloys in combination with the needs of sulfuric acid industry. These alloy materials basically cover the materials required for each process of sulfuric acid production, and can meet the requirements of sulfuric acid production equipment. XDV XDSS alloy has been successfully applied from sulfur combustion to purification, conversion and dry absorption to HRS. Among them, the research and development of XDSS high silicon stainless steel for high temperature concentrated sulfuric acid is listed in the national Torch Development Plan. It has obtained a number of national patents and awards.
