WARNING
in accordance with international and
Clean out all pipelines before installation of the
regulator and check to be sure the regulator has not
been damaged or has collected foreign material during
shipping. For NPT bodies, apply pipe compound to
the external pipe threads. For anged bodies, use
suitable line gaskets and approved piping and bolting
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.
2. Silicone (VMQ) is not compatible with hydrocarbon gas.
3. Do not use in high aromatic hydrocarbon service.

practices. Install the regulator in any position desired,
unless otherwise specied, but be sure ow through
the body is in the direction indicated by the arrow on
the body.
Note
The recommended pressure limitations are
stamped on the regulator nameplate. Some type of
overpressure protection is needed if the actual inlet
pressure exceeds the maximum operating outlet
pressure rating. Overpressure protection should
also be provided if the regulator inlet pressure
is greater than the safe working pressure of the
downstream equipment.
Regulator operation below the maximum pressure
limitations does not preclude the possibility of damage
from external sources or debris in the line. The
regulator should be inspected for damage after any
overpressure condition.
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.

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 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.
