The ceramic-lined valve has very good performance on abrasion erosion, corrosion resistance, excellent heat-shielding, and electric insulation. Mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment, and other industries where the metal valve cannot be applicable.

What is a Ceramic Ball Valve?

A ceramic ball valve is a type of ball valve which has internal components made of ceramic materials. Such ceramic components include ball, seat, and lining. A ceramic ball valve has its body made of a metallic material such as stainless steel or carbon steel. The metallic body is used to protect the ceramic trim from damage by sudden mechanical or thermal shock. A ceramic ball valve uses a ball with a hole at its center where fluid flows through when the handle is rotated. Ceramic ball valves can also be automatic by using actuators like pneumatic, electric, or hydraulic actuators. Benefits of using a ceramic ball valve over other materials like steel include lower mass and high resistance to wear. Ceramic ball valves have excellent resistance to corrosion and abrasion. Such properties of ceramic ball valves are used in severe applications prone to abrasion and corrosion. Ceramic ball valves are used in various industries such as petroleum, chemical engineering, and manufacturing plants.

The ceramic ball valve adopts a new high-tech type structural ceramic material as sealing and wearing parts, which can improve abrasion and corrosion resistance, and sealing performance, prolonging lifespan, 2-4 times of lifespan than Titanium Alloy and Monel valve. Using ceramic ball valves can reduce repair or replacement costs and improve the safety, and stability of the operating system.

Components of Ceramic Ball Valves

Trim components of ceramic ball valves adopt Alumina or zirconia ceramic with high chemical stability and hardness (HRC88), only inferior to diamond. The ceramic-lined valve has very good performance on abrasion erosion, corrosion resistance, excellent heat-shielding, and electric insulation. Mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment, and other industries where the metal valve cannot be applicable.

The ball is made with advanced grinding equipment and advanced process technology that can ensure high precision ball roundness, a good surface. The self-lubricating capability of ceramic ensures good sealing after polishing, which radically changed the defects that metal hard sealing valve has such as big torque, and non-corrosion-resistant sealing surface.

The ball and seat adopt alumina or zirconia ceramic with high chemical stability and hardness (HRC88). The ceramic-lined valve has very high abrasion resistance, corrosion resistance, erosion resistance, and good insulation. The wetted body is fully lined with PFA that also has good performance on corrosion resistance. Compared to the fully lined ceramic valve, PFA lined one lower the whole weight and is also more economic.
