Manual Ceramic Lined Ball Valve for Slurry Mining Chemical China

Manual Ceramic Ball Valve

Manual ceramic ball valve is a valve made of ceramic materials (such as alumina, silicon carbide) with sealing components or spheres. It can be quickly opened and closed by manually rotating the handle/handwheel to drive the sphere to rotate 90 °. Its core advantages lie in its super strong wear resistance and corrosion resistance, which can withstand high hardness particles, acidic and alkaline media, and high temperature and high pressure working conditions. It has reliable sealing and long service life, and is suitable for harsh environments such as power, chemical, and mining.

Wide adaptability

Wide adaptability
01
Suitable for complex media containing particles, fibers, etc. (such as slurry, pulp) and high-pressure, high-temperature scenarios, covering multiple fields such as power, metallurgy, and sewage treatment.

Economy and maintenance convenience

01
Long lifespan and low cost
The lifespan is 2-4 times that of titanium alloy valves or Monel valves, reducing replacement frequency and maintenance costs.
02
Convenient maintenance
Some structures support online maintenance (such as replacing valve seats), without the need to disassemble the valve as a whole, reducing downtime.

Optimized sealing and operational design

01
Precision sealing pair
The ceramic sphere is finely ground and tightly matched with the valve seat, utilizing the self-lubricating properties of ceramics to achieve low friction sealing and extremely low leakage rate.
02
Low operating torque
The ceramic ball has a low friction coefficient with the valve seat, making opening and closing operations easy and reducing manual operation intensity.
03
Low flow resistance design
When fully open, the flow channel is close to the pipeline cross-section, reducing pressure loss and improving fluid transmission efficiency.

Core properties of ceramic materials

Core properties of ceramic materials
01
Super abrasion resistance: The valve body and sealing components are made of high hardness ceramics such as alumina and silicon carbide (Rockwell hardness HRC90), which can resist the erosion of high hardness particles and significantly extend the service life.
02
Corrosion resistance: Ceramics have strong chemical stability and are resistant to strong corrosive media such as acids, alkalis, and salts. They are suitable for corrosive environments such as chemical and petroleum industries.
03
High temperature resistance: Ceramic materials have excellent high temperature resistance and can operate stably under harsh conditions such as high temperature steam and hot fluids.
