Metal Seated Ball Valves

FMX Series (3-pc High Performance)
The A-T Controls M Series metal seat ball valve is designed for use in severe services such as high temperature, high pressure, and abrasive fluids found in Oil & Gas, Petroleum, Petrochemical, Chemical, Power Generation, Pulp & Paper, and Mining industries.
FMX Series: 3-Piece High Performance Metal Seat Ball Valve Features:
- Oversized stem design prevents deformation at higher pressures and temperatures
- Larger ball design provides better sealing to prevent leakage
- ANSI Class 600 wall thickness design
- Bidirectional design for backflow application
- Inconel® spring design to maintain good contact between ball and seats during operation
- Live-loaded packing design and dual anti-static devices eliminate stem leakage while providing longer life cycle
- Blowout proof stem
- ISO 5211 mounting pad
- Fire safe design conforms to API 607 4th Edition
- Optional Tungsten Carbide (TC) coating for heavy slurry & high temperatures
