Special ceramic valve
As a professional supplier of ceramic ball valves in the world, KSINO is not only committed to the production of various ceramic valves, but also has been committed to the research and development of new ceramic materials. Y-TZP and Ce-TZP are widely used because of their high strength, good wear resistance, good chemical stability and other characteristics. However, due to their thermal shock resistance, they cannot be used under high temperature conditions. As the ball core of valve, its toughness is limited, which may lead to broken ball in case of jamming or locking. In order to meet the increasingly complex and harsh service conditions of ceramic valves, especially the higher service temperature, we have developed a magnesium oxide partially stabilized zirconia ceramic (Mg-PSZ) with excellent thermal shock resistance, and after continuous research and experiment, continuous innovation, we have developed a composite ceramic material with excellent thermal shock resistance and toughness comparable to metal.
The composite ceramic material developed by our company is made of metal and ceramic powder mixed and sintered. The metal elements can be Ti, Cr, Ni, Co, etc., which can be used alone or in combination, or other alloy powders. The selected metal elements have no chemical reaction with ceramic powder, the thermal expansion coefficient is close, and the wetting ability between metal and ceramic particles is good. Ceramic elements provide the ability to bear loads and wear resistance, while metal elements endow them with impact resistance toughness. Therefore, the composite ceramic material has a series of excellent properties, such as high strength and hardness, good toughness, good wear resistance, small coefficient of thermal expansion, high modulus of elasticity, good thermal shock resistance and good chemical stability, which can not be obtained by using only metal or ceramics. Although its corrosion resistance is reduced due to the addition of metal elements, its toughness and thermal shock resistance are significantly improved, which can not only meet the requirements for use under high temperature conditions, but also avoid broken balls due to jamming or locking.

Advanced ceramic valve
The applications of metal valves has a history of more than one hundred years. Although the structure and materials have also been improved during the period, they are limited by the conditions of the metal materials themselves. It is increasingly unable to meet the needs of severe working conditions such as high wear and strong corrosion under special environment. The frequent leakage caused by short service life and poor sealing affects the stability of the system operation to a certain extent.
