Fire Safe Series 40 butterfly valves for controlling flammable and hazardous fluids are bidirectional and feature fire-safe seats. In normal service, the Fire Safe combination RTFE/metal-seat seals bubble-tight in both directions of line media flow through the full rated pressure and temperature ranges. In the event of a fire, if excessive heat destroys the RTFE seat materials either partially or completely, the Fire Safe backup seat provides a constant, metal-to-metal seal.
