startup
The regulator is factory set at approximately the midpoint
of the spring range or the pressure requested, so an
initial adjustment may be required to give the desired
results. With proper installation completed and relief
valves properly adjusted, slowly open the upstream and
downstream shutoff valves.
adjustment
To change the outlet pressure, remove the closing cap or
loosen the locknut and turn the adjusting screw clockwise
to increase outlet pressure or counterclockwise to
decrease outlet pressure. Monitor the outlet pressure with
a test gauge during the adjustment. Replace the closing
cap or tighten the locknut to maintain the desired setting.
Taking Out of Service (Shutdown)
!
WarNiNg
to avoid personal injury resulting from
sudden release of pressure, isolate
the regulator from all pressure before
attempting disassembly.
