Chemoil Advance Technology supplies Bellow Seal Valves from recognized manufacturers for industrial applications where reliable stem sealing and reduced fugitive emissions are important. Bellows-sealed valve designs use a flexible metal bellows to isolate the valve stem from the process fluid, providing an additional barrier against external leakage through the stem area.

These valves are particularly suitable for applications involving steam, hot fluids, toxic or hazardous media, chemicals and other process services where minimizing fugitive emissions and maintaining reliable isolation are important considerations.

The bellows assembly is incorporated into the valve's sealing arrangement to provide a controlled barrier around the stem during valve operation. Depending on the application, bellows seal technology can be supplied with different valve designs, including gate and globe valves, with suitable body, trim and bellows materials selected according to the process conditions.
