NOTE： SG VALVE can not be installed to the accumulator which gas volume is less than 1 liter (exclusive).

Select the applicable gauge referring the above table. Our pressure gaugecontaining glycerol is a specially ordered product where the angle of thescale on the scale plate is shifted to the left side at 10 degrees. If theaccumulator is installed vertically, install the pressure gauge by putting halfof the maximum scale right above so that the pressure gauge can beprevented from becoming loose from the connected thread between thepressure gauge and the SG Valve due to vibration.

Select the applicable gauge referring the above table. Our pressuregauge containing glycerol is a specially ordered product where theangle of the scale on the scale plate is shifted to the left side at 10degrees. If the accumulator is installed vertically, install the pressuregauge by putting half of the maximum scale right above so that thepressure gauge can be prevented from becoming loose from theconnected thread between the pressure gauge and the SG Valve dueto vibration.

Application For North and South For All The World Except North For All The WorldAmerican Countries and South American Countries

The free rotation type gas charging 3-way valve can easily beattached to and detached from the accumulator just by rotatingthe set nut. It provides convenience especially when gascharging is done at a narrow space or when the gas charge valveis attached to the accumulator with a gas charging hoseconnected.The free rotation type gas charging 3-way valve has stopper andso excessive open / close handle turning can be eliminated.

We adopt 1/2-20UNF thread on the gas valve of theaccumulators for the north and south American countries for25MPa or lower pressure service. Attention shall be paid on themodel when ordering the gas charge valve.

The above adapter is availablefor connection of the gascharging hose to localnitrogen gas bottles in Japan.

Use pressure gauge capablefor approx. 1.5～3 times gaspressure to be precharged.(Please see page 22.)

Suitable hoses with fitting areto be used.Standard length of the hose is2m.

Please refer to 1. of page 22 about theItem Number.
