The FL-HT gate valve is part of the F Series of valves, which have been supplied for production and drilling service since 1958. Many of the features of the FL-HT gate valve are common to our original Type F gate valve, such as fullbore, forged construction; metal-to-metal sealing; a slab gate; and design simplicity. In other areas such as seat seals and stem seals, the FL-HT gate valve design takes advantage of our latest technology in materials and seal design. In addition, the FL-HT gate valve is rated for API Temperature Class Y, 0 to 650 degF [–18 to 343 degC], and high-temperature steam service.
