    In addition to fluoroelastomer seats that resist a wide range of chemicals, these valves have no metal parts to corrode, so they’re often used for chemical-processing applications in corrosive conditions. All bolt to flanges for adjusting and regulating flow in flanged pipelines. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 7/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes to help align the valve between the flanges.
    Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

    These valves meet NSF/ANSI 61 for use with drinking water. They bolt to flanges for adjusting and regulating flow in flanged pipelines. All have seven flow-adjustment positions. The lockable lever handle can be fixed in place using a padlock (not included) with a shackle diameter up to 7/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes to help align the valve between the flanges.
