Butterfly Valves | PVC & Plastic Valves

Manual and Actuated Polypropylene Butterfly Valves

Description

The FK Series Polypropylene Butterfly Valves incorporate many features of our industrial FK valve, yet the all Polypropylene construction and EPDM liner make this valve the perfect choice for water and light industrial applications. The special trapezoid shape of the liner and serrated body cavity guarantee a bubble tight seal while keeping break-away torque at an absolute minimum. This versatile valve features double self-lubricating seals, direct actuator mount capability, or the option of either a lever handle or gear box.
