Fully-welded insulation ball valves are a type of ball valve that integrates full-welded structure and insulation functions. They control fluids through the rotation of the ball, featuring high-sealing and thermal insulation properties.

Structural Features

Utilizing a full-welded construction, all components are joined through 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 changes to ensure sealing reliability.

Insulation design

By using a jacketed structure (welded carbon steel pipe or integral design), pipeline heat loss is minimized. Suitable for transporting high-viscosity, prone-to-solidify media (such as heavy oil, resins), with a temperature resistance range of -196℃ to +650℃.

Application Scenario

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