The valve shutter is a safety system
developed to prevent secondary accidents due to earthquakes,
and to forestall gas explosions and gas poisoning
due to gas leaks, using an emergency shutoff valve
on the gas cylinder. |
| · |
Having thoroughly considered explosion
prevention, the operating signals use air pressure
so that compressed air, nitrogen gas, etc. (0.29
Mpa) can be used within the plant, and a power spring
is used in the shutoff valve mechanism. |
| · |
One-touch mounting on existing gas cylinders
is possible. |
|
| |
 |
 |
Safety |
|
|
|
| · |
The valve can be closed automatically,
manually, or by remote control. |
| · |
The valve can be closed by linking to
a safety device such as a gas leak detector. |
| · |
There is an NC (normally closed) function
to close the valve if the operating signal is cut
OFF. |
| · |
The device has a failsafe function,
so there is no need for a secure power supply. |
