Johnson Controls VG7251GT 1/2" 2-Way N/O Globe Valve Body 4.6Cv

The Johnson Controls VG7251GT is a 2-way, normally open, union globe valve body used in HVAC application. It has a pipe size of 1/2 inch and a Cv of 4.6 that represents its flow coefficient. This valve is usually incorporated in a bigger control package that utilizes air pressure to control the flow of the liquid within the system. When the valve is in its normally open state it means that the valve is open when there is no signal. Under pressure the valve stem closes the internal passage to limit flow of the compressed air. This fail-safe design means that the valve will be opened again in the event of loss of air pressure. Its application covers a broad range of HVAC equipment, such as chilled water systems, heating systems, Air handling units and the like. By carefully regulating the rate of flow of the fluids.
