Mark 56 Series – Air Loaded Back Pressure
The Mark 56 is a highly accurate and economical air loaded, back-pressure regulator that provides regulation from a local or remote station. The operation of the Mark 56 requires no control spring or pilot. Instead, a static air signal is applied to the top of the diaphragm to determine the setpoint.
The LowFlow JR regulator is ideal for controlling the pressure load to the top of the diaphragm.
