DESCRIPTION
Dome Loaded, High Accuracy
The Mark 56/560 Series is a highly accurate and economical air loaded back pressure regulator that provides regulation from a local station or from a remote station. The Mark 56/560 requires no control spring or pilot. Instead, a static air signal is applied to the top of the diaphragm to determine the setpoint. These valves can be coupled with an extended range I/P for remote operation. It can also be manually controlled with a MK12 loading station or a LowFlow JR regulator.
