Butterfly Valves
To isolate and control the flow of fluid via a segment of stainless steel piping, butterfly valves are utilised. They are employed in applications requiring sanitary processes and are particularly well-liked in the brewing, beverage, dairy, and food industries. The valves are made of 316L stainless steel, have a manual 12 position PVC handle, and come in RJT, IDF, DIN, and SMS male to male ends in addition to plain weld ends and clamp ferrules. All alternatives described can function at pressures of up to 10 bar (150 psi) and are simple to assemble.

Flow coefficients (CV) = flow rate in gallons per minute of
water at 68O
F that will flow through the valve with a 1 psi
pressure drop. The CV values shown in the table are
calculated with the valve fully open.
