Dome valves with cylinder actuation is a kind of valve developed by FREE-VALVE company for dust removal system of coal fired power plant. Due to use a spherical-shape dome and an inflatable-seal to ensure a 100% air tight seal,it greatly improves the reliability of the whole system.

The seal is a loose component ,the dome valve has a tight sealing and it is easily removed for inspection.

During operation, the dome valve provides a full-bore and unrestricted flow of material, which does not impact on the dome and prolong the service life,so the capability of transporting dry ash is greatly increased.

The valve is “self-cleaning”,The inflatable-seal is only inflated when the valve is fully closed. This avoids shearing or jamming of particles between the seal and dome, and hence increases system reliability.

Dome valve with customized structural length and connection size is available.
