Wear Resistant Ceramic Slag Discharge Valve

A pipeline control valve designed specifically for high wear media, using a structure with a carbon steel valve body lined with ZTA engineering ceramics, and achieving pipeline opening and closing through gate lifting. The sealing surface adopts a ceramic ceramic or ceramic metal hard sealing combination, which enhances the sealing performance by utilizing medium pressure and is equipped with a protective lip structure to prevent hard objects from damaging the sealing ring. Suitable for discharge systems containing solid particles such as slurry, ash, wastewater, etc., with a working temperature of 400 ℃ and a pressure resistance of ≤ 6.4MPa, the service life is more than 10 times longer than that of ordinary alloy valves.

Energy saving and lightweight design

Energy saving and lightweight design
01
The flow resistance coefficient is as low as 0.02-0.03, reducing pressure loss by 30%; Carbon steel valve body with ceramic lining structure, weighing 20% -30% lighter than similar metal valves.

High temperature resistance and corrosion resistance

High temperature resistance and corrosion resistance
01
Temperature tolerance range -29 ℃~450 ℃, acid and alkali corrosion resistance (pH 0-14), suitable for strong acid (sulfuric acid, hydrochloric acid), strong alkali and salt spray environments.

Multi mode driver adaptation

Multi mode driver adaptation
01
Supports manual, electric, and pneumatic drives, with an electric response time of less than 1 second and an error control within 1mm. Some models use split valve bodies to achieve quick replacement of ceramic lining.

Self reinforcing sealing technology

Self reinforcing sealing technology
01
Ceramic ceramic or ceramic metal hard sealing combination, utilizing medium pressure to enhance sealing performance; Protect the lip structure to prevent hard objects from cutting the sealing ring, support bidirectional sealing, and withstand pressure up to PN16-PN40.

Anti blocking flow channel structure

Anti blocking flow channel structure
01
Full diameter straight through or Y-shaped flow channel design, avoiding dead corners of medium flow, combined with slag guide groove to automatically remove slag slurry, reducing the risk of particle accumulation and blockage at the bottom of the valve body.

High hardness ceramic materials

High hardness ceramic materials
01
Using engineering ceramics such as aluminum oxide（Al₂O₃）and silicon carbide (SiC), the hardness reaches HRA88 or above, and the wear resistance is 5-10 times that of traditional metal valves. It can withstand the erosion of media containing 30% -60% solid particles.
