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.
