DOME VALVE CONCEPT
MACAWBER BEEKAY’S DOME VALVE IS SIMPLE IN CONCEPT BUT REVOLUTIONARY IN PERFORMANCE.
Dome Valve: When open, it allows unobstructed flow path to material ensuring prolonged life, making it most reliable and least maintenance prone. An inflatable pneumatic sealing ensures an airtight seal in closed position which provides dust free environment and saves energy. Dome cuts through the moving or static column of material ensuring proper closing. A mere quarter turn is sufficient to move the dome valve from “closed” to “open” position.
Unique features make the Dome Valve inherently more efficient, highly reliable, and long lasting as compared to other types of valves like butterfly, cone, plate, flap etc. Dome valve’s capability to open & close with tight pressure seal works efficiently in harsh environments for abrasive materials. The valve finds its application in Power Generation, Cement, Iron, Mineral, Ferrous / Non-ferrous, Chemical etc industries for bulk material handling. Options of BULK-HEAD or IN-LINE valves are available to suit a specific requirement.
Dome can be made available in Cast Iron / Alloy Cast Iron / Stainless Steel to meet application demand. Dome valves can be actuated using either pneumatic / hydraulic cylinder or vane actuator. Dome valves are manufactured after going through stringent quality checks at Macawber Beekay’s state of art manufacturing units using CNC machines with highest accuracy levels.
