Pressure Tiers of City Gas in Japan and Product Category
High pressure city gas which is sent from the production plant is reduced to medium
pressure using pressure governors and distributed to large-scale plants and facilities.
The pressure is further reduced to low or intermediate pressure for distribution to regularhouseholds and commercial facilities. Relative city gas facilities including our governors
are typically designed based on following pressure tiers in Japan.

Converting the Flow Rate and Reading the Performance Curve

Step 1：Selecting Model CodeSee the char ts below and select a model code (range) based on your required inlet (P1)and outlet pressures (P2).

●Char t 1 For Medium Pressure Inlet

Flow rate is expressed in m3/h (normal) of 0.6 speciﬁc gravity natural gas in this catalogue.
If you use any other gas, please convert it using the following formula. Substitute the coeﬃcient of
conversion of your gas type into K in the conversion formula below to convert the ﬂow rate.

Step 2：Selecting Size

*See page 41〜42 regarding zero governors andequalizing regulators.
*As for PRAD, REGIT, WGX and meter regulators,
contact our local branch or agency.

Check the maximum ﬂow rate on the selected model code page and choose a governor
to meet your requirement.

Step 3：Gas Application

The ﬂow rates will vary depending on diﬀerent inlet pressures and maximum & minimum limits
on outlet pressures even at the same set point. You can see how much gas ﬂows through yourselected governor with in your acceptable pressure range (= oﬀset).
The curves represent the characteristic of a governor at each inlet pressure .

See page 5〜6 and ensure the gas to be used is applicable for the model. At the same time,
conﬁrm if the governor can ﬁt your other conditions of use such as our declared hydrostaticand air-tightness pressure and working temperature range, to satisfy all requirements.

N m3/h, m3/h（normal）

Meters cubed per hour (normal) ; measurement of volume rate of a gas

Speciﬁc Gravity

Step 4：Checking Piping Details

The rate of weight of a given volume ﬂuid to the weight of equal volume
of liquid/gas at stated temperature.

Oﬀset

The deviation from set point for a given ﬂow.

Flow Rate

The rate of ﬂow through the regulator speciﬁed by the manufacturer fora given inlet & outlet pressure and oﬀset.

Maximum Flow Rate

Our guaranteed ﬂow rate at maximum for which the governor performs at
its optimum at the declared outlet pressure for the declared inlet pressures
within the range of delivery (=oﬀset).

Conﬁrm that the type of connection and face-to-face dimension of the governor to ﬁt in
the piping atthe installation site.
Pressure losses due to length of piping, valves, pipe joints and ﬂow meters and so on shall betaken into consideration.
This catalogue indicates ﬂow rates measured under static conditions. Select the governor with amargin for your required capacity especially when there is a momentary pressure ﬂuctuation due
to solenoid valves rapidly turning on and oﬀ.

H5-EX（S）-NR・ H5-EX(S)-NR is a meter regulator from medium pressure to low pressure.
・ Designed to supply gas for low pressure meters.
・ Even if you convert a gas from LPG to NG after installation, you can change
the set point from LPG to NG by an easy operation. To do this remove an
inner adjusting screw and it will still ensure a proper and stable gas supply,
there is no need to exchange your ﬁxed-type meter regulator and no needto adjust it manually.

■With External Adjusting Knob

Gas Mixing by Venturi Mixer

Gas Mixing by Equalizing Regulator

The venturi mixer draws in gas by ejecting air at high pressure through the inner
nozzle. The gas pressure is reduced to zero (atmospheric pressure) by the zero
governor & makes gas proportional to the amount of air drawn in.
The governor maintains constant air and gas ratio even if the amount of air changes
due to the opening and closing of the butterﬂy valve.

The equalizing regulator keeps the upstream pressure of the oriﬁces on
the gas line as the same as an air line by loading the air to the regulator
cover vent from the air line. It ﬁxes the air ratio to be mixed.
The regulator maintains constant air and gas ratio even if the amountof air changes due to the opening and closing of the butterﬂy valve.

Oriﬁce

SGX-ZT range has an external knob
ﬁtted on the cover cap to make small
adjustments to the set point without
removing the head cover thus keeping
the original loading pressure sealed in
the cover.

・ Simply install it on the pipeline and this direct- operated valve performs
its function.
・ The large diaphragm in these valves gives extremely sensitive and stable

device temporarily supplies“City Gas”(Natural Gas) when emergencies
Package ・ This
shut down gas supply lines.

One-Way Lock Valve

・ It switches gas supply from city gas sourced tomixed gas by the New PA.
“One-way lock valve” system prevents improper
valve operation occurring.
・ A locking panel ﬁxes a valve in closed status
should another valve be opened at the same time.

・ Mixing propane with air to create a synthetic gas identical to city gas.
・ Easy operation. Touch the screen to start-up with the audio guidance.
・ For your safety and security, automatically performs gas leakage test.

Propane Air Mixer‒MX-500W

Notes

・Mixes LPG with air to provide similar gas property to NG, to allow NG distribution
to continue even during emergency or maintenance.
・The control panel stabilises mixed gas properties, keeps the ﬂuctuation within
the preset value based on the feedback from the calorimeter when the feeder
gas composition remains constant.
・This will be achieved even with the butane rich LPG.
