Keep reading to learn what you need to know about replacement seats for FLS gate valves.
How an FLS Valve Seat is Constructed
Just as with other components in FLS gate valves, the construction of the seat is crucial for performance. It’s also important to know what other parts are needed for seat replacement and to ensure they are equally well-constructed. For example, the seat for the FLS gate valve requires both an inner and outer diameter seal that is spring energized. The inner diameter should be machined to spec so there is no unnecessary erosion and no obstructed flow. Erosion could lead to premature failure of the valve.
FLS seats are made from 410 stainless steel and have a tungsten carbide face to improve the performance of the seat in terms of sealing and provide a longer life cycle due to the hardness of tungsten carbide.
Sizes and Pressure Ratings
Seats for the FLS style slab gate valve are available in sizes ranging from 1-13/16” to 7-1/16”. Pressure ratings available for the FLS style seats are 2,000 PSI to 15,000 PSI.
