The Jordan Valve Mark 56 is an air-loaded back pressure regulator. It operates with a static air signal that is applied to the diaphragm of the product. This allows the system to determine the setpoint (which can be easily adjusted).
The Mark 56 has a turndown ratio of 40:1 and has no minimum differential pressure requirement. It can be regulated from a local station or from an optional remote station, and it can be controlled manually with a MK12 loading station or LowFlow JR regulator.
