Zhejiang concealed ceramic knife gate valve

Pneumatic concealed ceramic knife gate valveWith a concealed rod structure design as the core, integrating pneumatic actuators and ceramic sealing technology, a compact and durable flow control device is formed. The valve body is made of high-strength cast steel or stainless steel material, with no cavity design in the internal flow channel. The gate is vertically raised and lowered in the side guide groove, and the bottom protrusion presses the valve seat to achieve sealing. The sealing surface is made of engineering ceramic materials (such as alumina and silicon carbide), which have high hardness and strong chemical stability, and can withstand the erosion of particle media in high-speed fluids. The valve drive mode is flexible and supports pneumatic, electric, manual and other modes. The pneumatic actuator drives the piston or rotating shaft through compressed air to achieve rapid opening and closing of the gate, which is suitable for remote automation control scenarios.

Performance Characteristics

Wear resistant and corrosion-resistant: Ceramic sealing surfaces have high hardness, strong resistance to particle erosion and chemical corrosion, and a service life several times longer than traditional metal valves.

Reliable sealing: The gate and valve seat adopt a hard sealing structure, and the ceramic material's self grinding characteristics can compensate for wear, achieving zero leakage sealing.

Low flow resistance: With a full bore design, the flow channel is smooth and unobstructed, reducing energy loss and improving system efficiency.

Compact structure: The concealed rod design reduces valve height, saves installation space, and is suitable for scenarios with dense pipelines or limited space.

Strong anti clogging ability: The sharp blade of the gate can cut fiber or granular media to prevent scaling and blockage, ensuring long-term stable operation.

Easy maintenance: Modular design supports quick replacement of seals or gate plates, without the need to disassemble the entire valve, reducing downtime costs.
