The unibody back pressure valve is the latest innovation to ensure leak-free connections and operation.

SERIES DETAILS:

The unibody back pressure valve ensures leak-free connections and operation and allows the flexibility of changing connection types for easy maintenance while eliminating additional system components (extra unions) to save you time and money.

As with all of the Griffco designs, the chemical feed system is safeguarded by applying a continuous back pressure to the chemical feed pump, while also acting as an anti-siphon valve to ensure increased leak-free reliability in the rigorous service of municipal and industrial applications
