3 Way ceramic lined ball valve adopts an optimized integrated structural design, mainly composed of a metal valve body, integral ceramic lining, ceramic ball core, ceramic valve seat, ceramic valve stem, sealing assembly, and driving device (manual, pneumatic, electric). The overall structure is compact, firm, and easy to install and maintain, with excellent pressure resistance and structural stability.
 

The outer valve body of 3 Way ceramic lined ball valve is made of high-strength carbon steel or stainless steel (WCB, CF8, CF8M) through integral casting and precision machining, which provides excellent mechanical strength, pressure bearing capacity, and structural rigidity. It can withstand system pressure and external mechanical impact without deformation. The inner wall of the valve body is fully lined with integral alumina (Al₂O₃) or zirconia (ZrO₂) ceramic lining. The ceramic lining is closely compounded with the metal shell through a special high-temperature bonding and mechanical fixing process, featuring high bonding strength, anti-stripping, and anti-cracking performance, avoiding lining falling off during long-term high-frequency operation.
 

According to different fluid control requirements, the valve is divided into T-type and L-type two mainstream structures, covering all three-way pipeline working conditions:

T-type 3 way ceramic lined ball valve: It can realize the interconnection, diversion, mixing, and full cut-off of three pipeline channels. It is suitable for fluid mixing, shunt delivery, and loop switching processes, enabling precise distribution and confluence of two different medium streams or branched delivery of a single medium. The flow channel is smooth and straight with low flow resistance, ensuring efficient and stable fluid transmission.

L-type three-way ceramic ball valve: It is mainly used for medium flow direction switching and two-channel cut-off control. It can quickly switch the fluid between two vertical pipelines and completely cut off the third channel. It is widely applied in pipeline reversing, branch pipeline opening and closing, and medium switching working conditions, with accurate switching stroke and zero residual flow.

In addition, a special 135° Y-type three-way ceramic ball valve is available for oblique pipeline systems, solving the flow dead zone and medium deposition problems of traditional right-angle three-way valves, and is more suitable for powder and granular medium conveying systems.
 

The ball core and valve seat are all made of high-density precision ceramics, processed by ultra-precision grinding technology to achieve high sphericity and flatness. The matching precision of the ball core and valve seat reaches the micron level, forming a reliable hard sealing pair. Different from soft-seal valves that are easy to age and wear, the ceramic hard seal has no deformation under high temperature and high pressure, realizing long-term zero leakage sealing performance.

3 Way ceramic lined ball valve stem adopts an integrated ceramic structure, which is coaxial with the ball core and rotates 90° synchronously. It is equipped with a high-temperature resistant and wear-resistant packing sealing assembly, which effectively prevents medium leakage at the valve stem. The rotating friction pair is optimized with self-lubricating ceramic formula, which greatly reduces operating torque, makes switching flexible and labor-saving, and adapts to high-frequency cyclic operation.
 

3 Way ceramic lined ball valve adopts industrial high-purity alumina ceramic (99% purity) and stabilized zirconia ceramic as the main medium-contact materials, which have far better comprehensive performance than metal materials such as stainless steel and alloy steel in harsh environments:

Excellent Wear Resistance: The hardness of engineered ceramics is as high as HRA85-92, second only to diamond. It can resist long-term scouring and friction of mediums containing solid particles, powders, and crystals, with a wear resistance 10-20 times that of traditional stainless steel valves, effectively avoiding valve cavity abrasion, channel deformation, and flow rate instability.

Superior Corrosion Resistance: Ceramic materials have stable chemical properties and are inert to most acidic, alkaline, salty, and organic corrosive mediums. They can resist the erosion of strong acid, strong alkali, brine, and corrosive gas, solving the problems of metal valve corrosion, rust, and medium pollution, and ensuring the purity of conveying mediums.

High Temperature & Pressure Resistance: The ceramic lining has low thermal expansion coefficient, good thermal stability, and no cracking or failure under high temperature working conditions (working temperature range: -20℃ ~ 450℃). The integral composite structure of metal shell and ceramic lining ensures stable pressure bearing performance, adapting to medium and high pressure pipeline systems.

Anti-Fouling & Low Flow Resistance: The ceramic surface is smooth and dense with ultra-low roughness, not easy to adhere to dust, powder, and viscous mediums. It avoids medium deposition and scaling in the valve cavity, maintains unobstructed flow channel for a long time, and reduces pipeline system energy consumption.

Long Service Life & Cost-Effective: Under abrasive and corrosive working conditions, the service life of lined ceramic ball valves is more than 8 times that of ordinary metal valves, greatly reducing valve replacement frequency, equipment downtime, and later maintenance costs, and improving the overall operating efficiency of the production line.
