Fuel Oil Burner Control

Mark 44 Series – Adjustable Cam

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.

Mark 53/54 Series – Differential Back Pressure

The Mark 53 maintains a constant differential between the inlet pressure and the pressure loaded on top of the diaphragm. It can be used for both differential and remotely adjusted applications.

Mark 63/64 Series – Differential Regulator

The Mark 63 is designed to maintain a constant differential between the pressure on the discharge side of the regulator and the signal pressure loaded on the diaphragm. The Mark 64 provides the same flow capacity as the Mark 63, but with less offset in controlled pressure due to a larger diaphragm.
