Marketing InformationIPEX® has expanded our line of FK Series butterfly valves to now include models with a CPVC disc. The glass reinforced polypropylene body of our FK Series butterfly valve combined with a CPVC disc provides the superior strength and chemical-resistance required to withstand the harsh demands of industrial environments. The specially designed trapezoidal shape of the valve liner combined with a serrated body cavity promote a bubble-tight seal while keeping break-away torque to an absolute minimum. Double self-lubricating seals keep the valve operating smoothly and efficiently.
