Griffco Corporation Stops

Griffco corporation stops are designed to ensure chemical feed systems inject into the center of a process stream for better mixing and to prevent corrosion along the process pipe. In addition, they allow for quill servicing without having to turn off or shut down the process or main line. 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. 

Materials of construction include PVC, CPVC, PVDF, 316 SS, Alloy 20 and Hastelloy C. They are available in sizes 1/2", 3/4”, and 1”.

Griffco corporation stops are threaded into a process pipe or tank to deliver chemical to a desired application point. The ball valve allows for separation of the process fluid and chemical being injected for servicing or isolations purposes. The integrated quill keeps the chemical off the wall of the tank or pipe and will ensure better mixing of the chemical with the process fluid. The ball check in the valve functions as a positive shut-off to ensure the process fluid does not go back up the chemical line. The union facilitates an easy connection between the valve and the chemical line. An optional flexible line is available to allow for removing or retracting the quill from the process or main.
