‌Manual Ceramic Strainer Valve‌ is a high-performance valve, especially suitable for mediums containing solid particles and particulates. Its main features include the use of ceramic material to manufacture the sealing surface and valve passage, offering advantages of wear resistance, corrosion resistance, and shape retention at high temperatures. The manual ceramic strainer valve is commonly used in pipelines of mining, power plants, petrochemical, metallurgical, and other industries, for the purpose of cutting off or connecting the medium in the pipeline.

Structural Features

The manual ceramic slag discharge valve features a sealing surface and valve passage made of ceramic material, enhancing the valve's wear and corrosion resistance, significantly extending its service life. Its structural design ensures no slag accumulation within the valve body, providing a tight closure, especially suitable for severe wear conditions. Additionally, the valve cavity is equipped with slag guide grooves, which automatically remove slag slurry, preventing the accumulation at the bottom of the valve and ensuring a secure closure.

Application Scenarios

Manual ceramic slag discharge valves are widely used in the following scenarios:

Mine: Used for coal, slag slurry, etc.

Power Plant Desulphurization: For ash slurry.

Petroleum Industry: Suitable for catalytic cracking systems and severe conditions with particulates.

‌Metallurgy Industry: Coal, slag slurry, etc. for steel industry use.

Pulp and Stock Water Mixture: For the papermaking industry.

Water Treatment Plant: Used for wastewater, sludge, refuse, and clarified water containing suspended matter.

Operation and Maintenance

Manually operated ceramic slag discharge valve is actuated by a handwheel, offering simple operation and low cost for both purchase and maintenance. It does not require complex electrical control cabinets or cylinders. During use, regular checks of the valve's sealing and wear should be conducted to ensure proper functioning. Additionally, the valve body's internal cavity can be treated to provide anti-scaling, anti-corrosion, and anti-wear properties, further extending its service life.
