Overview
Excelling in severe service flow control applications
Leading Metal-Seated Valve for Power and Mining Industries
Bray M1 Series severe service metal-seated ball valves deliver exceptional performance and reliability in the most challenging fluid control conditions. The M1 Series severe service isolation valves are designed for high-temperature, high-pressure, corrosive, and erosive service conditions, critical applications, and lethal service, suitable for power generation, mineral and mining, oil and gas, refining, chemical/petrochemical, agricultural chemical, and specialty industries requiring absolute safety and reliability. The M1 Series severe service ball valve features superior technology with a heavy-duty drive train, 360° Mate-Lapped ball and seat, live-loaded packing, heavy-duty ISO 5211 actuator mounting, an innovative stem alignment method that eliminates stem side-loading and ensures extended packing life, and proper thermal spray technology including HVOF (High Velocity Oxygen Fuel), APS (Atmospheric Plasma Spray), PTA (Plasma Transfer Arc), laser cladding, and other metallization coatings for extended service life in severe conditions, minimizing downtime. M1 Series valves are custom-designed and manufactured for specific applications, with careful consideration of process conditions required for your industrial fluid control process. Our engineering and process applications team are industry leaders with expertise in designing metal-seated ball valves and will closely analyze your fluid conditions and process chemistry, including: temperature, pressure, thermal shock risk, abrasion, corrosion, cavitation, flashing, solids handling, and flow velocity to select appropriate construction materials and valve trim. As a leading ball valve manufacturer with operations in 400 locations worldwide, Bray™ is committed to creating value for our customers through high-performance severe service ball valves designed and manufactured with the highest quality and workmanship in the industry.
