Bellow Seal Valves
Bellow Seal Globe and Gate Valves
Bellow Seal Globe & Gate Valve
Chemoil Advance Technology supplies Bellow Seal Globe and Gate Valves from recognized manufacturers for reliable process isolation and flow service where reduced stem leakage and fugitive emissions are important. The metal bellows sealing arrangement provides an additional barrier around the valve stem, helping minimize the escape of process media through the stem area.
The range combines two commonly used valve designs for different process requirements. Bellow Seal Globe Valves can be selected for isolation and flow regulation where appropriate, while Bellow Seal Gate Valves are primarily used for reliable on/off isolation in pipelines and process systems.
