Jordan Back Pressure Regulator
Russ Bailey
A large chemical facility was having problems with their air header pressure dropping when occasional high usage occurred on a non-critical leg of their system. Rather than install a separate air system or a control loop to prevent the usage to deplete the air pressure on the critical leg of their system, they utilized one simple Jordan valve.
A Jordan Back Pressure Regulator was installed on the non-critical leg, and it was set at a point that was minimum for safe operation on the critical leg of the system. Under normal conditions when the header pressure was high, the back pressure regulator would remain fully open allowing full pressure to both legs of the system.
In the event that exceptionally high air consumption depleted the header pressure to the critical minimum point, the back pressure regulator would throttle the non-critical leg header allowing more air to get to the critical leg of the system.
This solution offered a simple, less costly alternative to a control loop and eliminated the need for an air system upgrade. It should be noted that Jordan Header Pressure Regulators are reliable for steam and liquid services so their approach could be used on those systems as well.
