Griffco Valve, Inc., located in Amherst, New York, has introduced its new line of high-pressure chemical injection valves (injection quills). Used as the transitional point for the chemical before it is injected into process piping, Griffco’s model IVQ injection valves feature dual-threaded NPT (National Pipe Thread Taper) connections in 1/2” (DN 15), 3/4″ (DN 20) and 1” (DN 25) sizes with standard quill lengths of 3” for 1/2” and 3/4” diameters, and 4” on 1” diameter models.
Featuring simplified, robust construction, the new injection valves/quills ensure that chemical feed systems inject into the center of a process stream for better mixing and to prevent corrosion along the process pipe, according to Griffco. A check valve helps keep the chemical secure and prevents backflow up the chemical line.
