What is the quality of silicon nitride ball valves

Silicon nitride ceramic material is a precision ceramic material with good high-temperature strength and excellent heat resistance and impact resistance. Silicon nitride ceramics have excellent mechanical, performance, and machinability properties, as well as advantages such as high-temperature resistant ceramics, corrosion-resistant ceramics, wear-resistant ceramics, magnetic insulating ceramics, insulating ceramics, and self-lubricating ceramics

Silicon nitride ceramics are an advanced structural ceramic material with unique high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, good oxidation resistance, thermal shock resistance, mechanical impact performance, as well as excellent properties such as low coefficient of thermal expansion, low coefficient of friction, anti magnetic, electrical insulation, and small specific gravity. It is considered by the material science community to be a high-tech new type of material with excellent comprehensive performance in the field of structural ceramics and has the potential to replace nickel based alloys in high-tech and high-temperature fields.

Main performance of ball valves

Ball valves have low fluid resistance; Quick and convenient switch; Small external dimensions; Lightweight; Seal well; Long service life; High safety and reliability; Convenient maintenance; And it is popular due to its features such as self pressure relief and ball sweeping. Especially in recent years, with breakthroughs in new structures, new materials, and processing techniques, its scope of use has become increasingly widespread. It can be used for various media, pressure and temperature conditions, and the diameter range is constantly expanding.

The working principle of a ball valve is to apply an external force to the upper end of the valve stem, driving the closing element (ball) to rotate 90 ° around the centerline of the valve body to complete the functions of cutting, connecting, distributing, or changing the flow direction of the valve.
