PRESSURE REDUCING SANITARY REGULATORS
I. DESCRIPTION AND SCOPE
Models PA1 and PL1 are pressure reducing regulators used to control downstream (outlet or P
outlet size 1/2" (DN15) and 3/4" (DN 20) with Tri-Clamp
stainless steel construction. Refer to Tech ni cal Bulletin PA1/PL1-TB for specific design conditions and selection
recommendations.
II. INSTALLATION
Installation of adequate overpressure pro tec tion
is recommended to pro tect the reg u la tor and
all downstream equip ment from dam age in the
event of reg u la tor failure.
1. An inlet block valve should al ways be installed
upstream of the regulator.
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.
The maximum outlet pressure is list ed on the
name plate as the upper range spring pres sure
level, and is the rec om mend ed "upper operative
limit" for the sens ing diaphragm (see Sec tion IV.
Startup, Step 7). Higher press ures could dam age
the di a phragm. (Field hydro static tests fre quent ly
destroy dia phragms. DO NOT HYDRO STATIC TEST
THROUGH AN IN STALLED UNIT; ISO LATE FROM
TEST.)

3. An outlet pressure gauge should be located
ap proxi mately ten pipe diameters downstream, and
with in sight.
4. All installations should include a downstream re lief
device if the inlet pressure could exceed the pres sure
rating of any downstream equip ment or the maximum
outlet pressure rating of the unit.
5. Flow Direction: Install so the flow direction match es
the arrow stamped on the regulator body.
6. Install unit with spring chamber (2) in the vertical
position to allow for proper draining.
