Mark 66 Series – Air Loaded Pressure Regulator

The Mark 66 is a highly accurate and economical air-loaded pressure regulator that provides regulation from a local or remote station. The operation of the Mark 66 requires no control spring or pilot. Instead, a static air signal is applied to the top of the diaphragm to determine the set point.

The LowFlow JR regulator is ideal for controlling the pressure load to the top of the diaphragm.
