DEMECH has supplied Flap valves having inlet size from 200 to 500 mm square. Whereas Cone valves upto of 400 mm diameter have been supplied.The valves need power to open but are closed naturally by counter-weights. The valves are fabricated from mild steel plates with access cover to inspect and attend to the Cone or Flap. Due to low and controlled speed, wear due to abrasive material is minimal. The entry and exit of chamber can be provided with liners for longer life. Cone and seat are casted in suitable wear resistant material to take care of abrasion. The flaps are fabricated either with replaceable liners of hard material or they are manufactured from hard plates like Sailhard or Hardox.The valves are either driven by electric motors or pneumatic hydraulic cylinders. To achieve the alternate and sequential operation, the motor driven valves have specially custom designed cam arrangement and the cylinder operated valves have a sequential timer based controller.

Double flap valve is continuous material discharge equipment. Double Flap Valve has a two door flap plate which open and close alternatively.

Whizz Engineering Services Pvt. Ltd. is one of the leading manufacturer and supplier of highly double flap valve in Pune. Double flap valves are a type of airlock valve commonly used in industrial applications as a component in bulk material handling applications. Double flap valves are primarily used to discharge chunky or fibrous, bulk materials from hoppers, bins, and cyclones operating under positive or negative pressure. Clients can avail this double flap valve at very reasonable rates.

Double flap valve is continuous material discharge equipment. Double Flap Valve has a two door flap plate which open and close alternatively. As the material falls on the top plate, during continuous operation the plate opens and discharges the material on the bottom plate. After discharging the material the top plate closes. This ensures that the DFV is sealed to prevent air leakage. The bottom plate then opens after the top plate is closed and allows material to fall onto onward collecting equipment. The cycle time is precisely adjusted such that after the bottom plate closes the top plate opens. Thus ensuring continuous air sealing across the DFV. The time for which both flap are in closed condition, is known as dwell time.

Double 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.
