摘要: A reusable emergency gas shutt-off valve for terminating the supply of fuel to a dwelling is adapted for fluid pressure actuation at a location outside of the dwelling, manual actuation on the valve itself, and thermal actuation from heat in the vicinity of the valve or via a signal received from a temperature-sensing device at a location remote from the valve. The valve is resettable only by utilizing a specially-constructed reloading tool.
