Product Overview
 This valve is suitable for high-hardness particles or soft particles   but corrosive medium pipe for opening and closing purposes. Nominal pressure 1.6MPA, to adapt to temperature less than or equal to 200 degrees. The   parts in contact with the medium are all structural ceramic materials   with high chemical stability and high hardness (Rockwell hardness   HRC90), second only to diamond. Therefore,   the valve has a very high wear resistance, corrosion resistance,   erosion resistance, and good thermal insulation, thermal expansion. Ball   using advanced grinding equipment and technology manufacturing, high   ball roundness accuracy, surface quality, with the seat on the research,   the use of ZrO2 ceramic self-lubricating, can achieve good sealing   performance. Ceramic   good wear resistance, so that the valve durable, high reliability, long   service life, titanium alloy valve and Monel valve 2-4 times.
