Compared to ordinary ball valves, wafer thin ball valves have significant advantages such as short structural length, light weight, easy installation, and material savings. Wafer insulated jacket ball valves provide excellent insulation. Additionally, the valve seat adopts an elastic sealing structure, ensuring reliable sealing and easy operation. Equipped with a fire-safe design, in case of a fire, it can still operate reliably and maintain good sealing. Upon user request, an anti-static structure can be included. A 90° switch with a perforated positioning plate is provided, which can be locked if needed to prevent misoperation.

Uses of Wafer Thin Ball Valves:
Wafer ball valves and wafer insulated jacket ball valves are suitable for various pipelines with Class150, PN1.0～2.5MPa, operating temperatures of 29~180℃ (sealing ring) or 29~300℃ (sealing ring). They are used to cut off or connect the medium in pipelines. Depending on the material selected, they can be applied to water, steam, oil, oxidizing media, urea, and various other media.
