Application
For isolating, calibration and draining (venting)
pressure gauges and transmitters.
Using the Isolate & Bleed Valves
In normal operation the “isolate” valve is open while the “vent” valve is closed.
To remove the instrument, first close the “isolate” valve, then open the “vent” valve to relieve
pressure upstream of the “isolate” valve.
Calibration option
By connecting a test gauge to the vent port, it is possible to check the calibration
of the installed instrument without removing it from the installation.
