Gas Valves

Installation of New Gas Valve Cap

For improved safety, we are working to attach new gas valve caps, more durable than conventional caps, to unused gas outlets not connected to any gas appliances.

Target gas valves

The new gas valve cap is intended to be fitted to gas outlets that meet the following two conditions.

  • Gas outlet (unused) not connected to any gas appliances
  • Gas outlet with a knob to open and close the gas valve (excluding fuse valves)

  • The new gas valve cap is more durable than a conventional gas valve cap. However, Osaka Gas Network will not be held responsible for damage caused by not closing a gas valve not connected to any gas appliances.

Replacement of Previous Models of Gas Valve

We recommend replacing previous models of gas valves with highly safe gas valves (for a fee). With a highly safe gas valve, the safety device will work to automatically shut off the gas if the rubber hose (soft gas cord) is detached.

  • Do not open the gas valve if no gas appliance is connected.
  • Be sure to properly fit a purpose-designed gas valve cap on unused gas valves. Replace if it has cracks or otherwise damaged.

Caution!
  • Do not disassemble or remove the gas valve.
  • When replacing a rubber hose (soft gas cord), be sure to close the gas valve.
    If you replace a rubber hose with the gas valve open, a gas leak will occur.

Inspection Port-Equipped Gas Valve in Cabinet

If there is an inspection port-equipped gas valve in your cabinet as shown in the figure, note 1 and 2 below.

  • Call the Gas Pipeline Helpline if the inspection port bolt is detached or loose.
  • Avoid setting the gas valve knob to a halfway position, but set it to the fully open or fully closed position.

Unused Threaded Gas Valves

Threaded gas valves not connected to any gas appliances must have a plug attached. If you accidentally open a threaded gas valve without a plug, it may cause a gas leak or fire.

Plug installation requires specialist techniques. For more information, contact Osaka Gas Network. Removing a gas appliance from a threaded gas valve also requires specialist techniques.

Gas Pipes

For Those Who Own and/or Manage a Building(s)

Deterioration of gas pipes may progress where not readily visible.

It is important to check gas pipe condition to prevent gas leaks and other accidents. We appreciate your understanding in this regard.

For example, gas pipes are installed in a location like this.
Gas pipes may in some cases be installed through a column (or a wall).

If you cannot check the gas pipe condition from outside, please consider newly providing an inspection port, by consulting a builder.

If an inspection port is provided:

  • When providing an inspection port, consideration should be given to the building structure and other elements.

Request for Avoiding Unauthorized Gas Construction

Apply with Osaka Gas Network for gas construction up to gas valves. Osaka Gas Network (or a gas construction company approved by Osaka Gas Network) will do the work. Please follow these instructions without fail to use the gas safely.

Please also note that any gas construction is prohibited by law (Gas Business Act) without the permission of the gas business operator.
