Mark 55 Series - Vacuum Service

Jordan vacuum back pressure regulators control very accurately and shutoff tightly to maintain the proper vacuum setting. They are used to maintain vacuums at predetermined settings and to regulate vacuum on evaporators, cookers, grinding fixtures, milking machines, altitude chambers, and other vacuum systems.
 
The lower vacuum acts beneath the diaphragm in the Mark 55. An increase in vacuum lowers the diaphragm and closes the valve; a decrease in vacuum raises the diaphragm and opens the valve. A clockwise turn of the adjusting screw increases the vacuum setting, while a counterclockwise turn decreases the vacuum setting.
