What is an SS 316 Ball Valve?

An SS 316 Ball Valve is a quarter-turn valve made from molybdenum-alloyed stainless steel, offering superior resistance to:

  • Chlorides (e.g., seawater, brine)
  • Sulfuric, nitric, and hydrochloric acids
  • High-pressure and high-temperature fluids
  •  Organic solvents, fuels, and harsh industrial chemicals
