The FK Series Polypropylene 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 torque at an absolute minimum. This versatile industrial valve features double self-lubricating seals, direct actuator mount capability, or the option of a lever handle or gear box. A stainless steel “insert” lug version provides full bi-directional operation allowing disassembly of the downstream flange connection without the integrity of the upstream line.
The FK Series Polypropylene Butterfly Valve is ideal for use in Commercial and Industrial Process Applications including Process piping systems, Double containment systems, Acid waste systems and wastewater, High purity systems, Municipal pressure and gravity piping systems, Plumbing and mechanical pipe systems, Electrical systems, Irrigation systems, and Radiant heating systems.
