Insulated Ball Valve

Insulated Ball Valve is designed for industrial pipeline applications where maintaining fluid temperature and reducing heat loss are important operational considerations. Its insulation jacket or thermal protection structure helps maintain the temperature of the medium and reduces the risk of solidification or excessive viscosity changes during transportation.

The valve generally adopts a ball-and-seat sealing structure, providing quarter-turn operation for opening and closing pipeline flow. Depending on the design, the insulation arrangement may incorporate an external jacket around selected body sections, allowing steam, hot oil, or another heating medium to circulate through the jacket. The specific jacket configuration depends on the process requirements and valve construction.
