Pneumatic ceramic feed valve

Pneumatic rotary feed valveIt is a valve that uses a pneumatic actuator to drive a rotating shaft and a valve plate to achieve opening and closing. Its core structure includes a valve body, a rotating shaft, a valve plate, a pneumatic actuator, and a sealing component. The valve body is made of high-strength cast steel or wear-resistant alloy material, and the sealing surface between the valve plate and the valve seat is covered with ceramic or hard alloy coating to ensure wear resistance and corrosion resistance. Pneumatic actuators are driven by compressed air to achieve fast and precise opening and closing of valves, suitable for installation in vertical or horizontal pipelines.

Pneumatic rotary feed valvePerformance Characteristics

Wear resistant and corrosion-resistant: The sealing surface of the valve plate and seat is made of ceramic or hard alloy material, with high surface hardness, which can effectively resist the erosion of particle media such as fly ash and slag, and extend the service life.

Reliable sealing: The sealing surface is designed with hard materials for grinding, which generates a self grinding effect during the opening and closing process, ensuring long-term sealing performance and reducing the risk of leakage.

Flexible opening and closing: The pneumatic actuator drives the valve plate to rotate, with low movement resistance and no jamming phenomenon, supporting frequent opening and closing operations.

High temperature resistance performance: It can adapt to high temperature working conditions, and some models use temperatures exceeding 350 ℃, meeting the needs of high temperature scenarios such as thermal power plants.

Easy maintenance: The pneumatic actuator is isolated from the medium, reducing the failure rate; Modular design facilitates quick replacement of seals or valve plates.

Application field

Thermal power generation: used in dry ash systems, pneumatic ash conveying pipelines, as feed valves, discharge valves, vent valves or drain valves, to achieve precise conveying and control of ash and slag.

Cement chemical industry: In the transportation system of bulk materials, such as cement powder, coal powder, and chemical raw materials, the opening and closing of pipelines is used to prevent material leakage or blockage.

Mining metallurgy: suitable for conveying pipelines of high wear media such as slag and tailings, ensuring stable system operation.

Papermaking and pharmaceuticals: used for pipeline control of viscous or corrosive media such as pulp and powder, reducing medium residue and pollution.

Environmental engineering: As a key valve in exhaust gas treatment and dust removal systems, it controls the flow of gas and improves purification efficiency.
