Griffco Unibody Relief

The Unibody back pressure valve ensures leak-free connections and operation. This design allows flexibility of changing connection types, provides ease of maintenance and eliminates additional system components (extra unions) saving time and money. As with all of the Griffco designs, the chemical feed system is safeguarded by applying continuous back pressure to the chemical feed pump, while also acting as an anti-siphon valve.
