INSTRUCTION AND MAINTENANCE MANUAL
HP400 HIGH PRESSURE REGULATOR
CAUTION:
These instructions should be read and
understood prior to installation, use, or maintenance.
GENERAL PRODUCT OVERVIEW
The HP400 Regulator is a hand operated, self-contained,
spring loaded pressure reducing regulator. This unit offers the
safety and reliable service of a piston sensed regulator.
The model HP400 has non-venting piston sensor and a
captured bonnet feature. An adjustable stop to limit the
maximum output pressure is standard.
MATERIALS OF CONSTRUCTIONS
The HP400 will operate with any fluid (liquid or gas) compatible
with the materials of construction. To identify the materials of
construction refer to the Control Engineering Data contained
on page 3.
Body Brass
Bonnet Brass
Main Valve Seat
Kel-F (Vespel Optional)
Sensor and Trim
300 Series Stainless Steel
Seals
Teflon / Viton (Buna-N Optional)
REGULATOR CLEANING
The HP400 Series High Pressure Regulators are 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
desired level of cleaning. Cost will be advised prior to
performing the cleaning operation.
CAUTION:
Maximum Supply Pressure 3500 PSI (24.20 MPa)
Maximum supply pressure can be derated based on
connection and internal material selections. See notes in CED
code (page 3).
An internal filter screen is provided in the inlet (“IN”) port only
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.
OUTLET PRESSURE RANGES
OPTION CODE
RANGE
“J”
20–2500 PSIG (0.14 -17.25 MPa)
PORTING CONFIGURATIONS
There are four (4) 1/4” NPTF connections on the HP400. The
supply connection port is 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.
Teflon thread tape is the preferred thread sealant when the
regulator is installed.
INSTALLATION
The HP400 can be line or panel mounted. For line mounted
applications refer to porting configurations for proper
orientation of ports.
Panel Mounting:
1. Remove handwheel, knob, or “T” bar handle and insert the
regulator from the rear of the panel.
2. Projection of regulator through the panel may be controlled
by adjustment of panel mounting nuts
3. Replace the handwheel, knob, or “T” handle.
4. Connect inlet, outlet and gauge ports as applicable.
PRINCIPLE OF OPERATION
Turning the control knob clockwise will increase the force on
the range spring and, in turn, the outlet set pressure.
Conversely, turning the control knob counterclockwise will
decrease the force on the range spring and decrease the outlet
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.
