Conoflow HP300 Instruction And Maintenance Manual

INSTRUCTION AND MAINTENANCE MANUAL
HP300 HIGH PRESSURE REGULATOR
CAUTION: These instructions should be read and
understood prior to installation, use, or maintenance.

GENERAL PRODUCT OVERVIEW

The HP300 Regulator is a self-contained, spring loaded
pressure reducing regulator. This unit is a piston sensed, self-
relieving regulator which allows a pressure setting reduction in
a closed system by relieving downstream pressure through the
regulator.
A Vespel main valve seat is utilized for bubble tight shut off in
dead-ended applications. Control pressure ranges can be
changed without removing the regulator from the process line

MATERIALS OF CONSTRUCTIONS

When a relieving style sensor is used, hazardous or corrosive
fluids should not be used. When the non-relieving sensor is
used the HP300 will operate with any fluid (liquid or gas) which
is compatible with the materials of construction. To identify the
materials of construction, refer to Control Engineering Data
contained on page 4.
Body Brass/303SS/N.A.C.E 316SS

REGULATOR CLEANING

The HP300 Series High Pressure Regulator is cleaned to ITT
Conoflow Specification ES8A 01 294.

OXYGEN SERVICE

Specification of materials in regulators used for oxygen service
is the USER'S RESPONSIBILITY. Cleaning for oxygen service
(per ES8A 01 297) to 3500 PSIG (24.20 MPa) is supplied by
ITT Conoflow at no additional cost. For special cleaning
requirements, the customer must supply specifications for the

WARNING
Conoflow's products are designed and
manufactured using materials and workmanship
required to meet all applicable standards. The use
of these products should be confined to services
specified and/or recommended in the Conoflow
catalogs, instructions, or by Conoflow application
engineers.
To avoid personal injury or equipment damage
resulting from misuse or misapplication of a
product, it is necessary to select the proper
materials of construction and pressure-
temperature ratings which are consistent with
performance requirements.

performing the cleaning operation.
CAUTION:
Maximum Supply Pressure
Stainless Steel
Brass
Maximum supply pressure can be derated based on internal
material selections. See notes in CED code (page 4).
WARNING:
The HP300 is a relieving regulator and should
not be used with hazardous gases.
A 20 micron filter is installed in the regulator to stop random
contamination resulting from installation. An auxiliary filter is
recommended for all but the cleanest fluid. Gaseous fluid must
be free of excessive moisture to prevent internal icing or
condensation during operation.

PORTING CONFIGURATIONS

There are four (4) 1/4" NPTF connection on the HP300. The
supply connection port in labeled "IN" and the supply gauge
port is labeled "HI". The outlet port is labeled "OUT" and the
outlet gauge port is labeled "LOW". Care should be exercised
when installing the high pressure line to assure it is connected
to the inlet ("IN") port, otherwise the regulator will not function
properly. See figure 1 on page 5 for port identification drawing.
Teflon thread tape is the preferred thread sealant when the
regulator is installed.
