The model PVB is a pressure vacuum breaker assembly. Production began in 1995. The division that produced backflow preventers was purchased by Watts Regulator in 2011. Production of these assemblies was discontinued in 2013. The body is of bronze construction. Both seats are replaceable. The check assembly is modular in construction. The test cocks for this model are located on the ball valves and not on the assembly body. In 2006 a modification was incorporated by lengthening the top of the body. A clip was added under the air inlet module in this newer version. In 2008 Flomatic offered the Wilkins 720A in sizes 1 1/2"-2" to complement their 3/4"-1" sizes.
