Double Cone Valve - Abrasion-resistant, High Vacuum Capability | Airtight Sealing, Dual Hopper Design, Efficient Dust Control

We are the largest Exporter, Manufacturer and Supplier of Double Cone Valve in Mumbai, Maharashtra, India. Double Flap valves find their application as a substitute of Rotary Airlocks i.e. to allow flow of dust and maintain airlock across the valve. It is particularly suitable for handling highly abrasive and gritty materials along with high vacuum across the valve. Two small hoppers are mounted in-line and with some space between them in an air-tight casing. Two sets of flaps/ cones seat against the discharge openings of the hoppers. The flaps or cones are held on arms that are fulcrum on two shafts. The shafts are provided with external counter weights to counter balance the weight of flap or cone, the connecting arms and also the material pressure on top. The counter weight is so selected that the flaps / cones close tightly against the seat rings fitted at the discharge end of the hoppers to avoid leakage. The flap/ cone mounting on the connecting arms self aligning type to make the sealing airtight. For cone dump valve, the seats are sometimes provided with additional rubber rings to ensure leakproofness. The drive mechanism of these valves comprises of a geared motor with cam or linkage that alternately turns the two shafts by some degree. This results in partial lowering of the flap pair or cone at two levels alternately.
