ABSTRACT:
A gas meter installation including gas supply plumbing and point of use plumbing will have a gas meter therebetween. A valve can be installed with the gas meter for shutting off the flow of gas to the point of use. This valve is preferably a gate valve mounted with the a gas meter, and can be retrofitted into existing installations, or installed with the new plumbing installation. The valve can be shut off by remote activation for example due to a seismic sensor causing a controller to send a signal to activate the valve. The control can also interact with electricity shut off apparatus, automatic meter reading apparatus and point of use security systems.
