7.2.6 Media flow control valve 

The media flow control valve 

(P4VL0174)

 is a sliding gate valve which regulates the flow of the media 

by altering the size of the orifice through which the media passes. The sliding gate is subjected to a 

continuous flow of media through it and hence it is being constantly eroded by the abrasive action of 

the media. The wear rate is dependent on the type and grain size of media in use and the air pressure 

within the pot. Regular inspection is necessary to ensure that the failure of the sliding gate does not 

lead to the destruction of the valve outer casing.
