Bellow Seal Manual Globe Valves

Chemoil Advance Technology supplies Bellow Seal Manual Globe Valves from recognized manufacturers for reliable process isolation and flow control in industrial applications where reduced stem leakage and fugitive emissions are important. The bellows sealing arrangement provides an additional barrier around the valve stem, helping minimize the escape of process media through the stem area.

The manual globe valve design uses a movable disc or plug to control the flow passage, making it suitable for isolation as well as flow regulation in appropriate services. Manual operation provides a simple and dependable method of valve operation without requiring an external actuator or control system.
