Sealed Insulated Ball Valve for High-Viscosity Fluids

The Insulated Ball Valve offers easy and rapid operation, with a simple 90° turn from fully open to fully closed. Its straightforward design ensures low maintenance and quick seal replacement. When in either full open or full closed position, the ball and seat sealing surfaces are isolated from the media, minimizing erosion and wear. The wiping action during operation also makes this valve suitable for fluids containing suspended solids.

To ensure reliable sealing at the stem, an additional sealing chamber with packing and gland is provided, preventing leakage even under varying temperature conditions. The valve’s insulation design effectively maintains media temperature and reduces heat loss along the pipeline, while its full bore design matches the pipeline diameter, ensuring efficient flow and minimal pressure drop.

This type of ball valve is widely used in industries such as petroleum, chemical, metallurgy, pharmaceuticals, and food processing, especially for transporting high-viscosity media that may solidify at normal temperatures. The thermal insulation enhances performance in both hot and cold media applications.

The Insulated Ball Valve can be supplied with various flange standards and sealing face types to suit different piping requirements. Multiple actuation methods are available, including manual, worm gear, electric, pneumatic, or hydraulic drives, supporting remote control and meeting diverse operational needs.
