 Long life ball seat 
 Seat sealing surface is stellite alloy or other alloy steel, ball sealing surface nitriding treatment or welding alloys, hard chrome plating, vacuum coating - tungsten alloy and Stellite and other forms; on the levels of temperature and high friction dust, slurry, solid foreign matter mixed in the pipeline to transport category, with a very high abrasion resistance and long life. 

 High precision ball high seat tightness 
 Metal valve seat, sealing difference is its weakness, our company has developed a very high metal sealing ball valve seal. Seat by a spring preload to ensure that when the sealing pressure, high pressure seal to ensure that by the piston effect seat, one of the most critical is our original sphere process to ensure that the sphere of high precision (roundness). Advanced seat structure, high precision ball tight seal constitutes a major factor, but also and a large lower operating torque. 

 Metal seat wide range of applications 
 General soft seat, easy to damage the valve seat half-open state, and some fluids can not be used, the narrow temperature range, uses limited. Our metal sealing ball high hardness metal seat for high temperature fluids, high friction dust, slurry, containing impactor media, foreign matter such as solid form, nearly all the fluid can be used. 

 All the features of both valve 
 Comparison of gate valve, globe valve, with more features of our metal seat ball valve, ball valve all the characteristics of both, small flow resistance, 90 ° stem rotation operation can be realized quickly shut down, manual, automatic conversion easy, easy automation. 

 The best fire safety valve anti-static 
 Metal valve seat, the limit resistance 500 ℃ high temperature, fire has a natural anti-static function. 

 The most economical combination of materials 
 Our metal sealing ball valve, according to the use of different conditions, use of different sealing, can achieve the most economical and reasonable choice. 

 Arbitrary choice of mode of operation 
 Our metal sealing ball valve, according to valve size and purpose, select a variety of operating mechanism.
