25. Gas Pressure Regulator
General information
Gas Pressure Regulator adjusts high-pressure gas to low pressure to release the gas with regular
pressured quantity. There is a high-pressure gas inside the regulator. Use the pressure-resistant device
and inspect it regularly to keep normal condition.
Preparation
1. The rust in regulator will cause troubles (gas leak, closure of gas path, etc). When installing to gas
cylinder, clean the cap of the cylinder completely. On new plumbing, remove all of the rust, water,
and lotion first.
2. When connecting regulator and gas cylinder, check that the gasket is inserted in position. If there is
no gasket or the gasket is damaged, use preparatory one.
3. On installing regulator to gas cylinder, use right sized spanner and tighten firmly. Check gas leak
after the installation.
Operation
1. Turn the pressure-adjusting handle to “CLOSE” or “SHUT” (counterclockwise) before gas supply.
Shut the valve on the exhaust to stop gas flow.
Do not turn handle to “OPEN” by force when there is no gas in the chamber
or the cylinder is not connected.
2. Open the valve of gas cylinder slowly and keep it to small amount until the gas fills with the chamber.
After the gas is full, open the valve fully.
Avoid standing right in front of the pressure meter
when opening or closing valve.
3. The regulator with high lateral pressure meter indicates the pressure at intake.
4. On the use of exhaustive pressure changeable regulator, the second pressure will be increased if the
from pressure adjusting handle or screw turned to the direction of “OPEN”. The range of adjustable
pressure is 60 to 70% of the maximum value of constant and lateral meter.
5. Open the valve of the exhaust to release gas.
Precautions
1. The safety valve is set to a safety pressure in consideration of the pressure normally used
2. Perform a gas leakage check by using soapy water or leakage detection fluid. If there is leakage, it
can sometimes be stopped by additional tightening. However, if the leakage is caused by wear or
damage to a part, it is necessary to carry out repair using genuine parts, so please contact your local
dealer or one of our sales offices for repair.
