ABSTRACT:
A gas leak detector incorporated in a rotary valve intended to be mounted in a gas system adjacent the source of gas, the detector valve having a first position permitting flow from the source into the system, and a second position in which any gas entering the system due to a large or small leak in the system is made visible as it passes through a bubble chamber. Alternatively, a U-tube monometer is used to indicate drop in pressure due to a leak in the system. Also two embodiments are arranged as to be assembled for left hand or right hand use, one of which is arranged to be held in TEST position, the valve moving to OFF position when released while in TEST position.
