The gas earthquake shut-off valve is composed of a valve body, a shut-off device and a trigger device. The valve body is formed by connecting an upper section and a lower section, and the shut-off device and the trigger device are arranged in the valve body. The trigger device is ...
We’ve hired Earthquake Tech twice, for Gas Valve Shut-off Installation and full Earthquake Retrofitting. In both cases, and in all of our interactions with the Earthquake Tech team, they have exceeded expectations. The work has been outstanding: on time, on budget and very thorough. And the...
An earthquake actuated automatic gas shutoff valve having a valve bottom portion with a generally horizontal floor having a ball seat and a valve seat surrounding a gas outlet passageway. A ball having an elastomeric outer surface is held in the ball seat and in the event of an earthquake, ...
and that metamorphic CO2may in turn play a role in the installation of the next inter-seismic regime. Alternatively, the still evolving CO2emissions in Syabru-Bensi, Timure and Chilime may also indicate a currently unstabilized system, able to diverge unpredictably. Given the issue of a pendin...
A control lever on the valve is held in the open position by a latch which fits into a latch groove in the end of the control lever of the valve; a spring is attached to the control lever to pull the valve shut when the latch is released. The shock waves of the earthquake move a...
