Using the 2-valve manifold
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.
Note: The body & trim parts on all 316/316L Valves & Manifolds comply to NACE MR-01-75 & NORSOK M-650 as standard.
N/ABy connecting a calibration gauge to the vent port, it is possible to check the calibration of the instrument without removing it from the installation.
