Sanitary Connections
The Tri-Clamp® and Cherry Burrell®® I-Line Fittings are quick-couple fittings for sanitary systems. This type of fitting provides a fast, efficient removal of the valve for cleaning. Other benefits include: non-contaminating environment, self aligning - minimizes turbulence, compact, and readily adaptable to other types of piping. The benefits of the quick-couple sanitary fittings, offer an ideal application when combined with the features of the QCI Rotor Valve.
