and 3/8" (DN8 and DN10) FNPT or 1/2" (DN15) with Tri-Clamp connections. The unit is suitable for gaseous or liquid
services. Refer to Technical Bulletin P1-TB for design conditions and selection recommendations.
II. INSTALLATION
Installation of adequate overpressure pro tec tion
is recommended to pro tect the reg u la tor from
over pres sure and all down stream equip ment from
dam age in the event of regulator failure.
1. An inlet block valve should always be installed.
2. If service application is continuous such that
shut down is not readily accomplished, it is rec-
ommended that an inlet block valve, outlet block
valve, and a manual bypass valve be installed.
3. Pipe unions should be installed to allow removal
from piping.
4. An outlet pressure gauge should be located ap-
proxi mately ten pipe diameters downstream, and
within sight.
5. All installations should include a downstream re-
lief de vice if the inlet pressure could exceed the
pres sure rating of any downstream equip ment or
the maximum outlet pressure rating of the unit.
6. Clean the pip ing of all foreign material including
chips, welding scale, oil, grease and dirt before
installing the reg u la tor.
