Oscillating ceramic feed valve overview

The rotary disc valve is made of ceramic sealing structure (gate and valve seat are wear-resistant ceramic structure), erosion resistance, good wear resistance. Large valve chamber design, rotary gate seal structure, opening and closing process gate spin, opening and closing flexible. It has the function of polishing self-cleaning and one-way sealing when the valve is closed. It is suitable for the transportation of dry ash, pulverized coal, slurry and granular material. It is commonly used in pneumatic conveying system for feeding, discharging and exhaust balancing. Fouling, no jam, simple maintenance, long service life.

Swing ceramic feed valve application

Wear-resistant ceramic valve is mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear and tear, strong corrosion, high temperature, high pressure and other harsh conditions, ceramic valve also shows its superior performance . Ceramic valve to meet the high wear and tear, the use of highly corrosive environment, especially outstanding feature is the long service life, the cost performance of ceramic valves is far superior to other similar metal valves. With the continuous development and progress of science and technology, ceramic materials from the formulation, molding, processing and assembly technology and other aspects of the technology is more mature and complete, ceramic valves with its excellent performance has been more recognized by the valve industry. The successful experience of using the manufacture of ceramic valves can also be applied to a wider range of engineering applications.

Swing ceramic feed valve structure characteristics

All parts in contact with the medium are structural ceramic materials, the chemical stability and high hardness (Rockwell hardness hrc90), second only to diamond. Therefore, the valve has high wear resistance, corrosion resistance, erosion resistance, and good insulation, thermal expansion.

Sphere using advanced grinding equipment and technology manufacturing, ball roundness, high precision, good surface quality, with the seat on the research, the use of zr02 ceramic self-lubrication, can achieve good sealing performance.

Completely changed the metal seal valve easy to leak, torque, seal the surface of the shortcomings of corrosion-resistant.

Ceramic good wear resistance, so that the valve durable and high reliability. Long life, is 2-4 times the titanium alloy valve and Monel valve. For high-hardness granular media, or soft particles but corrosive medium, the valve has an absolute unparalleled advantage, is currently the only suitable medium for such valves.
