Pneumatic Ceramic Butterfly Valve

ALIS Valves offers Pneumatic Ceramic Butterfly Valves for industrial applications requiring automated flow control and high resistance to abrasive wear. These valves combine a rotating butterfly disc with ceramic components incorporated into selected wetted or sealing areas, depending on the design. Ceramic materials provide high hardness and wear resistance, helping protect critical valve surfaces against erosion caused by abrasive particles and selected aggressive process media. A pneumatic actuator uses compressed air to rotate the disc, enabling remote operation and integration with industrial automation and process control systems. Depending on the application, the valve body, ceramic grade, sealing arrangement and actuator configuration can be selected to meet the required operating pressure, temperature and media compatibility. Proper actuator sizing and consideration of ceramic component limitations are important for dependable operation in demanding industrial environments.

Pneumatic Ceramic Butterfly Valves are used in mining, mineral processing, cement production, chemical processing, power generation and other industries handling abrasive fluids or particulate-laden process streams. Depending on the valve construction and material compatibility, they may be suitable for selected slurry applications and other services where erosion resistance is important. Important selection factors include valve size, operating pressure, temperature, process media, particle size and hardness, ceramic material, sealing requirements, actuator torque and compressed-air supply pressure. Buyers should also confirm the required operating function, such as on-off control or modulating flow regulation, along with the actuator’s control accessories and fail-safe requirements where applicable. Ceramic components can be sensitive to impact and thermal shock, so the complete valve assembly must be suitable for the actual process conditions. Selecting the appropriate valve and pneumatic actuator configuration helps support automated operation, abrasion resistance and reliable service within the specified operating limits.
