Product features
  • Ball and seat hardened by hard alloy spray technology, precision grinding, zero leakage with reduced torque.
  • Valve shaft blowout prevention design, bottom T structure to ensure the valve chamber abnormal overpressure and packing pressure plate failure in extreme cases of safe and reliable,the valve shaft is hardened at the contact with the valve body to prevent the shaft from breaking due to torsion abrasion.
  • Bi-direction bubble tight, zero leakage*
  • Seat back spring loaded, adjusted according to temperature and pressure changes, to ensure the valve in high temperature and large temperature conditions stable operation.
  • The design of dustproof and slag in the spring chamber can prevent the particles from entering into the spring chamber in the process of medium circulation and effectively avoid the spring failure.
  • Separate packing compacting structure design, can be independently adjusted and field replacement of packing. The filler can be selected to meet the requirements of international emission standards.
  • Its design has "fire safety" high temperature resistance characteristics, anti - static structure.

Metal seal ball valve suitable for high temperature, high pressure, wear resistance, corrosion resistance and other working conditions, gas and solid two phase mixed flow, liquid, solid two phase mixed flow, high viscosity, high fiber, high temperature steam and other media cut off the ideal product, in petrochemical, oil and gas, coal chemical industry, power plant, polysilicon and other industries have a very wide range of applications.
*Zero leakage refers to the "Class A leakage" in accordance with the current international standards ISO 5208 and EN 12266-1, and the requirements of "Elastic Sealed Valves" of API 598.
