API 6A slab-style gate valve
The FL gate valve is the standard product offering for 5,000-psi [34.5-MPa] working pressure. It has served the industry with distinction for many years across a range of application types worldwide and is well tested, both in assembly and component qualification testing. This gate valve also offers exceptional service life with minimal maintenance and provides a low life cycle cost compared to other 5,000-psi valve designs.
Many of the features of the FL valve design are common to our Type F gate valve, which was introduced to the market in 1958: forged construction, metal-to-metal sealing, a slab gate, and design simplicity. In other areas such as seat seals and stem seals, the FL valve design takes advantage of our latest technology in materials and seal design.
