Contact SupplierDouble Cone Flap valves are used for controlled feeding as well as achieving air lock sealing. These valves consist of two independent Cone Flap valves mounted one upon other with their opening and closing alternated and synchronized to ensure that only one valve opens at a time.
DEMECH manufacture these valves to suit the opening sizes and required through-put rate. The through-put of these valves depend on the holding volume of the upper valve chamber and the rate of operations.
These are very slow operating valves as the operation cycle rate does not usually exceed beyond 6 cycles per minutes. Thus these valves have a batch feeding pattern rather than continuous feeding.
Selection of Cone or Flap depends on the characteristics of material to be handled and system requirement like pressure sealing. Cone valve has a better sealing than the Flap valve. However, in smaller size valves the Cone can act as an obstruction in the flow resulting in clogging of the small opening. The Cone valves usually have round opening whereas the Flap valves can have square.
