Introduction
Scope of the Manual
This manual provides instructions for the installation,
adjustment, maintenance and parts ordering
information for the Type HSR residential and/or
industrial/commercial pressure regulator.
Description
The Type HSR direct-operated, spring-loaded regulators
with internal relief provide economical pressure
reducing control in a variety of residential, commercial
and industrial applications. These regulators can be
used with natural, manufactured or lique ed petroleum
gases. In addition, the Type HSR regulator has
internal relief across the diaphragm to help minimize
overpressure. Any outlet pressure above the start-todischarge point of the nonadjustable relief valve spring
moves the diaphragm off the relief valve seat, allowing
excess pressure to bleed out through the screened
spring case vent.

Principle of Operation
Figure 2. Type HSR Pressure Regulator Operational Schematic
Refer to Figure 2. When downstream demand decreases,
the pressure under the diaphragm increases. This pressure
overcomes the regulator setting (which is set by a spring).
Through the action of the pusher post assembly, lever and
stem, the valve disk moves closer to the orice and reduces
gas ow. If demand downstream increases, pressure under
the diaphragm decreases.
Spring force pushes the pusher post assembly downward and
the lever, stem and valve disk move away from the orice.
The Type HSR regulators include an internal relief valve
for overpressure protection. If the downstream pressure
exceeds the regulator setting by 7-inch w.c. to 1.25 psig /
17 to 86 mbar, depending on the main spring used, the relief
valve opens and excess gas escapes through the vent in the
upper spring case.

To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate code,
regulation or standard) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to a regulator
could cause personal injury and property
damage due to escaping gas. To avoid such
injury and damage, install the regulator in a
safe location.
A regulator may vent some gas to the
atmosphere in hazardous or ammable gas
service, vented gas might accumulate and
cause personal injury, death or property
damage due to re or explosion. Vent a
regulator in hazardous gas service to a
remote, safe location away from air intakes or
any hazardous location. The vent line must be
protected against condensation or clogging.
WARNING
!
Personal injury, equipment damage or
leakage due to escaping gas or bursting of
pressure-containing parts might result if these
regulators are overpressured or installed
where service conditions could exceed the
limits for which the regulators were designed
or where conditions exceed any ratings of
the adjacent piping or piping connections.
Before installing the regulator, check for damage which might
have occurred in shipment. Also check for dirt or foreign
matter which may have accumulated in the regulator body or
in the pipeline. Apply pipe compound to the external threads
of the pipeline and install the regulator so that the ow is in
the direction of the arrow cast on the side of the body. The
diaphragm actuator assembly can be rotated to any position
relative to the body, in 90° increments. Remove the two cap
screws (key 17) that hold the body to the actuator in order
to rotate the diaphragm actuator assembly.

Do not install the regulator in a location where there can be
excessive water accumulation, such as directly beneath a
downspout or in an undrained pit.
To obtain the maximum ow capacities or other performance
characteristics, the length of pipe from the regulator outlet
to the meter—or for the rst 18-inch / 457 mm, whichever is
closer—should have no bends and should be the same size
as the regulator outlet. Replace the regulator if water gets into
the spring case or the lower casing of the regulator.
HSR Series regulators have a spring case vent
(1 or 3/4 NPT) which is screened to prevent insects or
foreign material from entering.
CAUTION
You are advised to use new vent piping
because defective threads on the relief
vent piping may interfere with the venting
assembly if the piping obstructs the
movement of the vent stabilizer.
On indoor installations, the vent should be piped outside
the building, see Figure 3. Remove the screen from the
regulator vent connection and connect vent piping from
that connection to the outdoors. Vent piping should be as
large in diameter as practical, be as short as possible and
have a minimum number of bends and elbows. Install a
weather and insect resistant vent assembly on the outside
end of the pipe, such as a Type Y602. The same installation
precautions apply to vent assemblies as the integral
regulator vents described previously.
A program of regular inspection of the vent opening should
be established to see that it has not become plugged by
foreign material. On some installations, such as in areas of
heavy snowfall, it may be necessary to install the regulator
beneath a protective hood. If other protection is provided from
the elements, the vent should be pointing or sloping down
suf ciently to allow any condensate to drain. Also check the
regulator periodically for external or internal corrosion.
Overpressure Protection
WARNING
!
Some type of overpressure protection is
needed if actual inlet pressure can exceed
the outlet pressure rating. Overpressuring
any portion of this equipment above the
limits given in the Speci cations section and
Tables 1 and 2 may cause damage to regulator
parts, leaks in the regulator or personal injury
due to bursting of pressure-containing parts or
explosion of accumulated gas.

Type HSR
Type HSR regulators provide internal relief that limits the
total outlet pressure build-up over setpoint. This internal relief
may be adequate for the application, if not, provide additional
pressure relief or a pressure-limiting device downstream.
Regulators should be inspected for damage after any
overpressure condition.
Startup
WARNING
!
To avoid personal injury or property damage
due to explosion or damage to regulator or
downstream components during startup,
release downstream pressure to prevent an
overpressure condition on the diaphragm of
the regulator.
In order to avoid an overpressure condition
and possible equipment damage, pressure
gauges should always be used to monitor
pressures during startup.
1. Check to see that all appliances are turned off.
2. Slowly open the upstream shutoff valve.
3. Slowly open the downstream shutoff valve.
4. Check all connections for leaks.
5. Make nal control spring adjustments according to the
adjustment procedures.
6. Light the appliance pilots.
Adjustment
To increase the outlet pressure setting of the regulator,
the adjusting screw (key 26, Figure 6) must be turned
clockwise. This requires removal of the closing cap (key 8).
To reduce the outlet pressure setting, turn the adjusting
screw counterclockwise. A pressure gauge should always be
used to monitor downstream pressure while adjustments are
being made. Do not adjust the spring to produce an outlet
pressure setting above the limit identied on the information
label. If the required pressure setting is not within the range
of the spring being used, substitute with the correct spring,
see Table 2. When changing the spring, also change the
range identied on the information label to indicate the
actual pressure range of the spring in use. After the spring
adjustment has been completed, replace the closing cap.
Shutdown
WARNING
!
To avoid personal injury or property
damage due to explosion or damage to
regulator or downstream components
during shutdown, release downstream
pressure to prevent an overpressure
condition on the regulator diaphragm.
Installation arrangements may vary, but in any installation it is
important that the valves be opened or closed slowly. These
steps apply to the typical installation.
1. Slowly close the downstream shutoff valve.
2. Slowly close the upstream shutoff valve.
3. Open vent valves downstream of the regulator.
4. Open vent valves upstream of the regulator.
Maintenance
WARNING
!
Avoid personal injury or damage to
property from sudden release of pressure
or uncontrolled gas or other process uid.
Before starting to disassemble, isolate the
regulator from all pressure and cautiously
release trapped pressure from the regulator.
Use gauges to monitor inlet, loading and outlet
pressures while releasing these pressures.
These procedures are for gaining access to the diaphragm,
valve disk and orice. All pressure must be released from the
diaphragm actuator assembly before the following steps can
be performed.
While using the following procedures, refer to Figure 6 for
key number locations.
Diaphragm Replacement
1. Remove the closing cap (key 8) and adjusting screw
(key 26).
2. Remove the spring case machine screws (key 9) out of
the spring case (key 1) and remove the spring case and
control spring (key 25).
3. Lift the diaphragm (key 11) slightly and slide it away
from the lever (key 4), so that the pusher post (key 12)
releases the lever.
6
Type HSR
4. Remove the relief spring retainer (key 14). Note the
direction of the spring retainer assembly to aid in proper
reassembly. Remove the relief valve spring (key 10).
5. Remove the diaphragm (key 11). Examine the
diaphragm and replace if necessary.
6. Reassemble in the reverse order of the above
procedures. Before attaching the spring retainer
(key 14) to the pusher post (key 12) to secure the
new diaphragm (key 11), place the loosely assembled
diaphragm into position in the lower casing (key 2),
being sure the pusher post is properly hooked on
the lever (key 4). Rotate the diaphragm so that the
diaphragm and lower casing holes align. Check the
diaphragm for proper orientation. The open slot in the
spring retainer is inserted from the notched side of the
pusher post. Install the spring retainer and proceed with
reassembly. Tighten the spring case machine screws
(key 9) to 15 to 30 inch-pounds / 1.7 to 3.9 N•m.
Valve Disk and Orice Replacement
1. Remove the cap screws (key 17) which hold the
actuator assembly to the body.
2. The regulator can be removed from the body, exposing
the disk (key 23) and the orice (key 22).
3. Examine the disk (key 23). If it is nicked, cut or
otherwise damaged, the disk should be removed from
the valve stem (key 5) and replaced with a new part.
4. Examine the seating edge of the orice (key 22). If it
is nicked or rough, it should be unscrewed from the
body with a thin wall 7/8-inch / 22 mm socket wrench
and replaced with a new orice to provide proper
shutoff. Treat the external threads of the new orice
with lubricant before reassembling, tightening to 25 to
35 foot-pounds / 34 to 48 N•m of torque.
5. Reassemble in the reverse order of the above
procedures. Tighten the cap screws (key 17) to
6 to 10 foot-pounds / 8.1 to 14 N•m.
Regulator Reassembly
As indicated by the square callouts in Figure 6 it is
recommended that a good quality pipe thread sealant be
applied to pressure connections and ttings and a good
quality lubricant be applied to O-rings. Also apply an antiseize compound to the adjusting screw threads and other
areas as needed.
