 Sanitary Air Augmented Pressure Regulators > Mark 96AA Series




Mark 96AA Series The Mark 96 with air augmentation (AA) option offers the same line sizes, Cv choices, seats, great low droop characteristics and stability of the standard MK96, but with an advantage. By connecting an air pressure signal to the 1/4" FNPT dome fitting via an air regulator or I/P, the set point chan be changed remotely by "sending an air signal instead of a technician".

The Mark 96AA gives users the ability to change pressure set points to any point in excess of the springs minimum set point (2 psi on a 3/4" - 1" Mark 96, 10 psi on a 1-1/2" - 2", and 15 psi on a 3"). Users adjust the regulator's spring to the lowest set point, or to the lowest set pressure that the regulator will operate at. To achieve a higher pressure set point, air pressure is added to the regulator dome.
