These fusion dampeners combine the technologies of Griffco Valve’s back pressure valves and pulsation dampeners. The new fusion dampeners simplify a chemical-feed system installation because they blend two previously separate accessories into one product. The initial offering of the products are available in NPT ¼-, ⅜- and ½-in. connection sizes. With a maximum operating pressure of 150 psi at 70°F, the new accessory covers a range of applications in the municipal and industrial markets.
