Article How It Works: Gate Valves
Stop, allow, or throttle the flow of process fluid with very low friction loss.
The FLS 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 FLS are common to our original Type F gate valve, such as
In other areas such as seat seals and stem seals, the FLS design takes advantage of our latest technology in materials and seal design.
The Cameron FLS gate valve is widely recognized as a high-quality valve for severe applications, available in pressure ratings from 2,000 to 20,000 psi and bore sizes from 1 13/16 to 11 in. The FLS valve is our standard valve for critical requirements, including extreme sour and subsea applications. In addition, it can be fitted with a wide range of our actuators.
