Ceramic wear resistant valves adopt high-performance structural ceramics. They feature good self-cleaning performance, ultra wear resistance, strong corrosion resistance, excellent self-lubricating property, long service life and wide operating environment, especially suitable for chemical industry.

In harsh environments such as chemical, coal and petroleum industries, metal valves can no longer meet the requirements of severe working conditions with high wear and strong corrosion, mainly reflected in easy leakage, large torque and corrosion-prone sealing surfaces of metal valves. Traditional metal valves are in urgent need of thorough innovation in materials, design and processing technology. Applying ceramic materials to industrial valves is a bold and beneficial innovation.

Metal valves are widely used in various industries with a history of hundreds of years. Although metal valves have been improved in structure and materials, limited by the properties of metal materials, they cannot adapt to increasingly severe working conditions of high wear and strong corrosion. The main problems are short service life and serious leakage, which greatly affect the stability of system operation.

Ceramic materials have small deformation and much higher mechanical strength than metals. Generally, the crystal ions constituting ceramic materials have small radius, high ionic valence and large coordination number. These properties make ceramic materials have extremely high tensile strength, compressive strength, elastic modulus and hardness. However, the brittleness and difficult processing characteristics of ceramics limit their application range. In the past decade, thanks to the development and progress of martensitic phase transformation toughening technology, composite material technology and nano-ceramic concept, the brittleness of ceramics has been greatly improved, their toughness and strength have been greatly enhanced, and their application scope has been continuously expanded. In recent years, new ceramic materials have been widely applied in petroleum, chemical, mechanical and other fields. Using the wear and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts to replace metal materials has become one of the important development directions in the high-tech material market in recent years.

Product Features: Material conveying systems in polysilicon, organosilicon, power plant, steel plant and other industries usually adopt pneumatic conveying or slurry conveying to improve system efficiency and reliability. However, high-speed solid materials during transmission seriously damage valve sealing surfaces and flow paths. SSZ engineers specially designed CDGV valves for this working condition, with maximum size up to 10". It is easy to assemble and maintain. The self-cleaning disc design allows micro-movement to avoid blockage by solid particles. Due to material characteristics, the sealing surface of CDGV series can resist impact from high-hardness materials, and its service life is several times longer than valves made of other materials.

Ceramic Eccentric Rotary Valve

Temperature: -29°C--320°C
Pressure: Class150#, 300#, 600#
Sealing Class: Class IV
Ceramic Material: Al₂O₃, ZrO₂, Si₃N₄, SiC
Stem: 17-4PH, HC, HB
Body: Optional WCB, 316, 304 and more

Product Features: Eccentric rotary valve serves for on-off or regulating control with large flow capacity. When fully open, the inner flow path of the valve is almost consistent with the inner diameter of the process pipeline without any obstructions. CREV provides perfect control solution for viscous media. The seat, plug and stem adopt eccentric design. Relying on the characteristics of ceramic materials, it can withstand severe working environments. At small opening control, the flow changes smoothly with high control accuracy. When the valve is closed, the plug generates lateral thrust to strengthen the contact between plug and seat and improve sealing performance.
