Design Features

Alumina ceramic water valve discs (also known as ceramic diverter filters) are key components designed specifically for water treatment 

equipment and fluid control systems, and are renowned for their excellent mechanical properties, wear resistance, and corrosion resistance.

Precision-machined orifices

The water valve disc contains multiple precision-machined orifices for precise control and filtration of water flow, ensuring efficient fluid 

dynamics.

High hardness and strength

The high hardness (Vickers hardness up to 15.7 GPa) and high strength (compressive strength 2000 MPa) of alumina ceramic enable the

 water valve disc to maintain stability and durability under high pressure and high flow rate conditions.

Superior corrosion resistance

Its excellent corrosion resistance prevents material corrosion and degradation when handling various chemicals and water flows, extending 

its service life.

Good electrical insulation and high-temperature stability

High electrical insulation (breakdown strength exceeding 10 KV/mm) and excellent high-temperature performance (maximum operating 

temperature up to 1650°C) allow it to operate safely in high-temperature environments.

Application areas

Water Treatment Equipment

As a key component in filtration systems, it is used for precise control and filtration of water flow, suitable for scenarios such as tap water 

treatment and industrial water reuse.

Fluid Control Systems

Used in high-precision fluid control equipment to regulate and manage the precise distribution of fluids, such as in chemical processing or 

pharmaceutical manufacturing.

Chemical and Pharmaceutical Industries

Used in high-end applications requiring precise fluid handling and chemical stability, such as the production processes of active

 pharmaceutical ingredients.

High-Temperature Industrial Applications

Due to its high-temperature stability and corrosion resistance, it is suitable for any system requiring fluid control under extreme conditions.

The superior performance and custom design of alumina ceramic water valve discs make them play a key role in modern industrial 

applications, particularly in water treatment and high-temperature fluid control. Their high durability and precise control capabilities
