Barnes & Jones vacuum breakers are simple, reliable devices that provide a positive means to automatically relieve or break an unwanted vacuum condition. Their rugged hex design provides for long service life and ease of installation. Bubble tight sealing is assured due to the soft silicon o-ring and spring pressure against the valve. They are suitable for steam boiler, process air heater, heat exchanger, and air/heat coil applications.
