SECTION I

I. DESCRIPTION AND SCOPE

The Model P2 is a pressure reducing regulator used to control downstream (outlet or P

) pressure. Available sizes

inlet/outlet port - 1/4" (DN8), 3/8" (DN10) and 1/2" DN15. The unit is suitable for cylinder gaseous service. Refer

to Technical Bulletin P2-TB for design conditions and selection recommendations.

II. INSTALLATION

re moved and not allowed to enter the regulator

upon startup.

8. Flow Direction: Install so the ﬂ ow direction match-

es the inlet stamp on the main regulator body (1).

9. For best performance, install in well drained hori-

zon tal pipe.

10. Basic Regulator - (Refer to Figure 2, Model P2):

Regulator may be rotated around the pipe axis

360°. Recommended position is with aluminum

knob (4) ver ti cal upwards.

11. Regulators are not to be buried un der ground.

12. For insulated piping systems, recommendation is

to not insulate regulator.

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. Strainers are rec om -

mend ed.

7. In plac ing thread seal ant on pipe ends pri or to

en gage ment, ensure that excess material is

CAUTION

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 reg u la tor failure.
