Structural features

The gate of the pneumatic ceramic knife gate valve usually adopts a blade-shaped design with a shearing function, which can cut off fibers, pulp and other debris in the medium to avoid valve blockage and ensure the smooth flow of the pipeline. It has two sealing surfaces, the most commonly used mode is a wedge design, and the wedge angle is usually 50 degrees. The valve body is reasonably designed, the structure is simple and compact, the channel is smooth, the flow resistance is small, and the energy loss of the medium during the flow process can be reduced.

Performance advantages

‌Reliable sealing‌: The pneumatic ceramic knife gate valve has excellent sealing performance, and mainly relies on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing. In the closed state, the gate can also be forced to press against the valve seat by external force to further enhance the sealing effect‌.

‌Wear-resistant and corrosion-resistant‌: The sealing surface and valve body are made of highly wear-resistant and corrosion-resistant ceramic materials, which improves the wear and corrosion resistance of the valve and extends its service life‌.

‌Easy to operate‌: pneumatic operation makes the valve opening and closing easier and faster, without the need for an additional power source‌

‌Low maintenance cost‌: Simple structure, easy to manufacture, install and maintain, reducing the cost of use‌.

Application scenarios

Pneumatic ceramic knife gate valves are widely used in various industrial fields, especially in the following scenarios:

‌Mining and steel industry‌: Used to handle media containing suspended particles and fiber materials.

‌Paper making industry‌: Handle pulp, fiber and other media.

‌Power station ash removal‌: Handle coal slurry, ash and other media.

‌Sewage treatment‌: Used in urban sewage treatment plants and industrial wastewater treatment systems
