PRESSURE REDUCING REGULATOR
I.
DESCRIPTION AND SCOPE
The Model 1000HP-5 and 1000HP-36 are cryogenic pressure reducing regulators used to control down stream
(outlet or P
) pressure to levels above 10 psig, and up to 300 psig (size dependent). Sizes are 1/2", 3/4", 1",
2
1-1/2" and 2".
The unit is designed for liquid or gaseous service with proper trim utilization, and proper jet selection.
Refer to Technical Bulletin 1000HP-CRYO-TB for sizing, application and selection recommendations.
Installation, operation and maintenance manuals (IOM's) exist for the following other Model 1000 products:
1000HP-Basic
II. INSTALLATION
1. An inlet block valve should always be in stalled.
2. If service application is continuous such that
shut down is not readily accomplished, it is
rec om mended that an inlet block valve, and a
manual bypass valve be in stalled.
3. Pipe unions must be installed to allow re mov al
from piping. Trim can only be changed by unit
removal from pipeline. If flanges are uti lized, a lap
joint flange is required on the inlet end of the valve
to help align bolt holes as the cylinder screws into
place.
4. An outlet pressure gauge should be located
ap prox i mate ly ten pipe diameters down stream,
and within sight.
5. All installations should include a down stream
relief de vice if the inlet pressure could exceed the
pressure rating of any downstream equip ment or
the maximum outlet pressure rat ing of the unit.
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.

The maximum outlet pressure listed on the name plate is
the "upper operative limit" for the sensing diaphragm.
Higher pressures could damage the diaphragm. (Field
hy dro static tests frequently de stroy dia phragms. DO NOT
HY DRO STAT IC TEST THROUGH AN INSTALLED UNIT;
ISO LATE FROM TEST.)
6. Clean the piping of all foreign ma te ri al in clud ing
chips, welding scale, oil, grease and dirt before
in stall ing the valve. Strain ers are rec om mended.
