Introduction

The Type HSR direct-operated, spring-loaded regulators 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
and have the same inlet and outlet pressure capabilities.

2

In addition, the Type HSR regulators have internal relief across
the diaphragm to help minimize overpressure. Any outlet
pressure above the start-to-discharge 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.

For each orice size, the outlet pressure setting is made with the same inlet pressure regardless of outlet pressure. Example: 3/16-inch / 4.8 mm orice uses 50 psi / 3.5 bar inlet for 5-inches w.c.

through 2 psi / 12 mbar through 0.14 bar outlet settings.

ORIFICE SIZE INLET PRESSURE FOR SET FLOWS

Principle of Operation

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 orice and
reduces gas ow. If demand downstream increases, pressure under the
diaphragm decreases. Spring force pushes the pusher post assembly
downward and the valve disk moves away from the orice. Type HSR
regulators include an internal relief valve for overpressure protection. If
the downstream pressure exceeds the regulator setting by 7-inches w.c.
to 1.25 psig / 17 mbar to 0.09 bar, depending on the main spring used,
the relief valve opens and excess gas escapes through the vent in the
upper spring case.

Installation

The HSR Series regulators may be installed in any position.
However, the spring case vent should be pointed downward. If
gas escaping through the Type HSR internal relief valve could
constitute a hazard, the spring case vent must be piped to a
location where escaping gas will not be hazardous. If the vented
gas will be piped to another location, obstruction-free tubing or
piping at least equal to the vent, and the end of the vent pipe must
be protected from anything that might clog it. Dimensions are
shown in Figure 6.

Type HSR Flow Capacity for Pressure
Factor Measurement

Tables 6 and 7 contain the ow capacities for the Type HSR at
accuracies of +/- 1% of absolute pressure. This data can be used
in applying the regulator in Pressure Factor Measurement (also
called Fixed Factor Measurement) or other applications requiring
better accuracy. Normally pilot operated regulators with high
accuracy are required for these applications. However, as shown
in the table, by ow testing and by limiting the droop on ow
capacity, +/- 1% of absolute pressure is obtained.

Overpressure Protection

The wide-open Cg for relief sizing (see Table 1) along with the

capacity information should be used in choosing appropriate
overpressure protection devices to ensure that none of the limits in
the Specications section are exceeded.

Overpressuring any portion of a regulator or associated equipment
may cause leakage, parts damage, or personal injury due to
bursting of pressure-containing parts or explosion of accumulated
gas. Regulator operation within ratings does not prevent the
possibility of damage from external sources or from debris in the
pipeline. A regulator should be inspected for damage after any
overpressure condition.

Capacity Information

The high efciency ow-through design provides maximum capacity
for a given orice size. Tables 8 through 1 give the HSR Series ow
capacities at selected inlet pressures and outlet pressure settings.
Flows are in SCFH (at 60°F and 14.7 psia) and Nm3/h (at 0°C
and 1.01325 bar) of 0.6 specic gravity natural gas. To determine
equivalent capacities for air, propane, butane, or nitrogen,
multiply the listed SCFH capacity by the following appropriate
conversion factor: air–0.775 for air, propane–0.628, butane–0.548,
nitrogen–0.789. For gases of other specic gravities, multiply the
given SCFH capacity by 0.775 and divide by the square root of the
appropriate specic gravity. If capacity is desired in Nm3/h, multiply
SCFH by 0.0268.

For Critical Pressure Drops

Use this equation for critical pressure drops (absolute outlet pressure
equal to one-half or less than one-half the absolute inlet pressure).

where,

For Non-Critical Pressure Drops

For pressure drops lower than critical (absolute outlet pressure greater
than one-half of absolute inlet pressure), use the following formula:
