Watts - 2" 765 PVB With Unions Ends

The FEBCO 765HUB 2" Pressure Vacuum Breaker with union connections is engineered to prevent backsiphonage in non-potable systems such as irrigation lines, cooling towers, pools, laundries, and industrial processes. This rugged unit features a bronze body, corrosion-resistant components, and a freeze-resistant engineered plastic bonnet. The unit combines a spring-loaded check valve and air relief valve in a single vertical assembly, protecting against contamination from backflow conditions. Union ends simplify installation and servicing, while the top-entry design provides full access to internal parts without removing the valve from the line. Ideal for high-flow systems requiring dependable performance and ease of maintenance.
