DOUBLE CONE VALVE

DOUBLE PENDULUM VALVE

In the double cone valves, the gates that block the passage of the material are conical. They are widely used in sinter plants, from tubes to electrostatic precipitators. They assure excellent tightness in the discharge of the material and, consequently, a longer lifespan for the machine. They can work with higher pressure differences than the Double Flap and Double Cup valves and are able to resist more severe abrasion conditions. They normally work in conjunction with knife gate valves.
