The Mark 44 adjustable cam valve is used to control the flow of fuel oil to a burner. It is ideally suited for process applications with frequent changes in fuel/air mixture because the valve can easily meet new requirements by simply readjusting the cam screws.
 
The valve is designed for applications where tight shutoff is not required; when required, it must be provided by other means.
