Griffco’s new Unibody pressure relief valves (leak-free relief valves) is the latest innovation to ensure leak-free connections and operation. This new 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 a continuous back pressure to the chemical feed pump, while also acting as an anti-siphon valve. This new construction ensures increased leak-free reliability in the rigorous service of municipal and industrial applications.
