Frequently Ask Questions
A High Pressure Dome Valve is a heavy-duty valve designed to isolate and control the movement of dry bulk solids, powders and abrasive materials under high-pressure process conditions.
Its dome-shaped closing element provides a robust sealing arrangement suitable for demanding applications.
Dome valves are particularly advantageous in applications involving abrasive dry solids and high-pressure pneumatic conveying, where a conventional butterfly valve may experience significant disc and seat wear.
Select suitable wear-resistant materials
Match the valve to the material characteristics
Maintain correct actuator pressure
Avoid operating outside rated conditions
Keep pneumatic air clean and regulated
Inspect sealing components regularly
Prevent excessive material buildup
The dome moves into position to open or close the material passage. During closing, the dome forms a seal against the corresponding sealing surface.
The exact operating mechanism depends on the specific dome-valve design.
A butterfly valve uses a rotating disc, while a dome valve uses a dome-shaped sealing element.
For highly abrasive dry solids and high-pressure conveying, a dome valve can provide better wear performance in suitable applications.
