ASH EXTRACTION VALVE

OVERVIEW

   
Ash extraction valve is used in Vacuum conveying system which is state between hopper and conveying line. Ash extraction valve is metal seated. Seat and disc is made from special alloy steel which gives better life than SS. During the operation gate operated by Pneumatic actuator and gate is away from the path of material, this feature helps to increase life of the valve & gives better performance than the slide plate of valve.

Body of valve is made in single piece. At discharge side access cover is provided for maintenance of seat and disc, and at rear side access cover is provided with poking rod. At bottom fluidizing pad is provided for assisting flow of material in vacuum line. These valves are recommended to use in the first, second field of ESP hopper / Bag filter.
