Injection valves ensure chemical feed systems inject into the center of a process stream.


Griffco injection valves (injection quills) are designed to ensure that chemical feed systems inject into the center of a process stream for better mixing and to prevent corrosion along the process pipe. The check valve prevents the process fluid from going back up the chemical line. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
