IPEX FK Series Butterfly Valves offer superior strength and chemical resistance in highly corrosive environments and process flow conditions. The special trapezoid
shape of the liner and a serrated body cavity guarantee a bubble tight seal while keeping break-away torque at an absolute minimum. This versatile industrial valve
features double self-lubricating seals and direct actuator mount capability. Pressure rated to 150 psi at 73°F. Sizes 2″ to 8″

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.
