Project Description

The PVB is similar to the AVB in its operation, however it contains two test cocks for inline testing, an inlet shutoff valve and an outlet shutoff valve. The PVB is ideal for continuous pressure health hazard. The PVB is designed to protect against backsiphonage and is not to be subjected to backpressure. Typically, the PVB is installed on multi zone irrigation systems.
