99% alumina ceramic seat holder

Common Applications Include: 1.Severe Service Ball Valves & Plug Valves:​ The protection tube would be placed around the valve stem. It prevents the corrosive, abrasive, or high-temperature fluid from eroding the metal stem, ensuring smooth operation and preventing seizures or leaks. 2.Knife Gate Valves:​ Used in industries like mining and pulp & paper to handle abrasive slurries. The tube protects the gate and stem mechanism from rapid wear. 3.Sensor Protection:​ It can serve as a thermowell or a sheath for temperature sensors (thermocouples, RTDs) or pressure sensors inserted into a pipeline. The alumina ceramic protects the sensitive sensor from chemical attack and physical damage. 4.High-Temperature or Corrosive Environments:​ Ideal for industries like: •Chemical Processing:​ Handling acids, alkalis, and solvents. •Petrochemical:​ In refineries with corrosive hydrocarbons. •Power Generation:​ In systems with high-temperature steam or flue gases. •Mining and Mineral Processing:​ For abrasive slurries and tailings. •Steel and Metal Production:​ In high-heat furnaces and handling molten metals.
