Cashco — MODEL HP HIGH PRESSURE REDUCING REGULATOR

image.png

                               FEATURES

High Pressure:

High inlet and outlet pressures; high
pressure drops.
Balanced Trim:

Minimizes the effect of large changes
in inlet pressure such as those
encountered with bottled gas.
Tight Shutoff:

Composition seat provides bubble-tight
shutoff.
High Capacity:

Allows banking of bottled gas thru one
regulator.
Adjustment Ease:

Radial roller bearings to reduce frictional
forces and wear on higher spring ranges.

APPLICATIONS
Designed primarily for controlling clean gases. Handles bottled
gas up to 3000 psig (207 Barg) inlet pressure, with a maximum
pressure drop of up to 2990 psid (206 Bard).
Use in liquid service is for non-cavitating fl uids up to 600 psid
(41.4 Bard) pressure drop, metal seated.

OPTION SPECIFICATIONS

This section indicates special variations which are available to the standard Model HP product. Multiple options may be selected;
i.e. HP-1+30, which is the standard HP product plus the -1 and the -30 Options together. Care must be exhibited to not develop
confl icting combinations; i.e. a carbon steel HP-55.


Option -1:

CLOSING CAP. Use to prevent
tampering with the set point pressure.
Available on all spring chamber
materials. Consists of a ductile iron
closing cap, a sealing gasket, a sealing
lock nut on the adjusting screw, and a
1/4” (DN8) NPT female tapped spring
chamber vent hole.
Option -1+6:

DIFFERENTIAL CONSTRUCTION.
For differential pressure service.
Available only on manganese bronze
or carbon steel spring chambers.
Internal construction includes a large
pusher plate and an extra diaphragm
gasket (for metal diaphragms). Limited
to the use of the lower range springs
indicated below, and maximum loading
containment levels indicated in Table 1.

Option -15:

STELLITED SEATS. Stellited seating
surfaces on unbalanced metal seating
piston and cylinder. Can only be applied
to Trim S1.
Option -25:

TAPPED VENT. 1/4” (DN8) NPT
tapped open ing in spring cham ber
for pip ing vent to re mote lo ca tion, in
the event of di a phragm fail ure.
Option -25P:

PLASTIC RAIN PROOF BUG
VENT. (includes Opt-25).
Option -25S: SST RAIN PROOF BUG VENT.
(includes Opt-25).
Option -30:

FLANGED END CONNECTIONS.
Welded-on 300#, 600#, 900#, and
1500# (PN50, 110, 150, and 260) raised
face fl anges available for carbon steel
or 316 SST bodies. Flanges and nipples
of same basic material as body. Nipples
and Flanges are socket weld design.
With 300# (PN50) fl anges, the
fl angepressure ratings are the pressure
limiting factors, not the body inlet ratings.
(Refer to Tables 9 and 10 for allowable
working pressure vs. temperature.).
With 600#, 900# and 1500# fl anges, the
body outlet is the pressure limiting factor
per Table 1.

See dimension “H” on Dimension
& Weight Table for face-to-face
dimensions of fl anged units.

Brit ish Stan dard Parallel Pipe
threads per ISO 7/1; used as an
al ter nate to NPT ends.
Option -32: EXTENDED NIPPLES. Schedule 160
plain end extension nipples available
for carbon steel or 316 SST bodies.
Nipples of same basic material as
body. Nipples are seal welded after
screwing into body. Refer to Table
11 for dimensions. NOTE: Used with
socket welded piping systems.
Option -34: SPECIAL 14” FACE TO FACE
DIMENSION FOR FLANGED END
CON NEC TIONS. See Opt.-30 for

gasket and fl uorocarbon elastomer
cylinder gasket over standard gaskets.
Temperature range: -20° to +400°F

body materials only. Cleaning per
Cashco Spec. #S-1134 for oxygen
gas service. NOTE: Design Pressure
Rating shall not exceed 290 psig (20.0
Barg) when body material is SST and
process medium is oxygen.

Option -56: SPECIAL CLEANING. Cleaned per
Cashco Spec. #S-1542. Utilize when
cleanliness level better than normal
is required and unit is not for oxygen
service. For all body materials. Not
