Double Cone Valve

Listing ID #3452014

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.
