The fully welded insulated ball valve is a ball valve that integrates full welding structure and insulation functions. It controls fluid flow through the rotation of the ball and features high sealing and thermal insulation properties.

Structural Features

Utilizing a full-welded construction, all components are joined by welding, eliminating bolt or flange structures and the risk of external leakage. The valve body is typically composed of a carbonized Teflon sealing ring and a disc spring, adapting to pressure and temperature variations to ensure sealing reliability.

Insulating design

Heat loss in piping is minimized through jacketed construction (welded carbon steel pipe or integral design), suitable for transporting high viscosity, prone-to-solidify media (such as heavy oil, resins), with a temperature resistance range of -196℃ to +650℃.

Application Scenarios

Ideal for conveying high-viscosity media that tend to solidify at room temperature in industries such as oil, chemicals, metallurgy, etc., it offers both automated control (electric/pneumatic drive) and low fluid resistance (bore size matches pipe diameter).
