Febco 765 Pressure Vacuum Breaker with 1-1/4" Ball Valve
The Febco 765 Series pressure vacuum breaker protects potable water lines from back-siphonage in irrigation, cooling towers, laboratories and commercial systems. This 1-1/4" assembly combines a spring-loaded check and an air opening port in one serviceable unit and includes integral 1/4-turn ball shutoffs for safe isolation during testing and maintenance. The bronze body and engineered bonnet provide corrosion resistance and freeze protection for long-term field performance.
