The FK Series Plastic 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.
- Standard ISO square dimensions for direct mounting of actuators.
- The disc/seat features a trapezoidal elastomeric liner to provide a bubble tight seal.
- The liner completely isolates the valve body from the process flow.
- The liner functions as a flange gasket on both sides of the valve.
- The body cavity features special channeling to prevent liner slippage and compression.
- Teflon® seated o-ring shaft seals.
- 1 1/2" to 12" Wafer Flange (ANSI 150)
