Main Performance of Imported Glass-Lined Diaphragm Valve

1. The glass-lined diaphragm valve applies porcelain glaze with high silicon content to the metal surface and is enameled at 950°C to make it tightly adhere to the surface of the metal iron substrate. Therefore, it has the dual advantages of chemical stability similar to glass and metal strength.

2. The working medium only contacts the diaphragm and valve body, and the control mechanism is separated from the medium path, which not only ensures the purity of the working medium but also prevents the possibility of medium in the pipeline impacting the working components of the control mechanism.

3. No separate sealing of any form is required at the valve stem. Therefore, this valve can ideally control multiple working media. The diaphragm is commonly made of elastic, corrosion-resistant, and impermeable materials such as rubber and plastic, making it especially suitable for handling chemically corrosive substances.

Performance Specifications

I. Corrosion Resistance: An Indestructible Fortress

The glass-lined layer of the imported glass-lined diaphragm valve, with silicon dioxide as its foundation, is melted at high temperatures, achieving极致 chemical stability. It can resist the erosion of various concentrations of organic acids, inorganic acids, weak alkalis, and organic solvents (special attention is required: hydrofluoric acid and fluoride-containing media, hot phosphoric acid above 180°C, and strong alkali solutions above 50°C should be used with caution). In industries such as chemical and pharmaceutical, stainless steel materials often struggle to withstand strong corrosive media like acids and salts, but the imported glass-lined diaphragm valve can handle them with ease, building an indestructible fortress for the production process. Different enamel formulations have varying acid resistance. Generally, enamels with higher silicon dioxide content, after high-temperature firing, offer superior acid resistance but relatively weaker alkali resistance. Therefore, we will tailor valves with comprehensive corrosion resistance to your specific working conditions, ensuring stability even in complex scenarios with alternating acids and alkalis.

II. Non-Stick and Easy-to-Clean Properties: Guardians of Hygiene and Safety

The glass-lined surface is smooth as a mirror, almost free of dead corners, making it difficult for materials to adhere and cleaning effortless. This characteristic provides an unparalleled advantage in industries with extremely high hygiene requirements, such as pharmaceutical production. Pharmaceutical production must strictly comply with GMP (Good Manufacturing Practice) requirements, meaning equipment containing drugs should have a simple structure, smooth surfaces, few dead corners, and be easy to clean to ensure drug purity and prevent bacterial contamination. The imported glass-lined diaphragm valve perfectly meets these stringent standards and is widely used in stages like active pharmaceutical ingredient (API) production. For any industrial scenario requiring system cleaning, it becomes one of the preferred valves for designers due to its glass surface's resistance to material adhesion.

III. Reliable Isolation and Purity Assurance: Guardians of Quality

After the inner surface of the equipment is coated with a glass-lined layer, the medium is effectively isolated from the iron-containing steel body, fundamentally eliminating the possibility of the medium dissolving iron ions. This is crucial for production processes with stringent raw material purity requirements, such as pharmaceuticals and dyes. In these industries, even trace impurities can affect product quality. The imported glass-lined diaphragm valve ensures high purity during fluid transportation and control, safeguarding product quality.

IV. Excellent Insulation Performance: Ensuring Safety and Stability

The glass-lined layer has excellent insulation properties. Under vacuum test conditions, a mere 0.4mm thick glass layer can withstand 20kV of voltage, providing strong assurance for the safe and stable operation of equipment.

V. Meticulous Craftsmanship, Quality First

The imported glass-lined diaphragm valve adopts internationally leading processes such as low-temperature entry and exit, cold spraying of porcelain enamel, and high-temperature slow firing. In the production process, stages like spraying, drying, enameling, and cooling are strictly controlled, with each cycle lasting approximately 12 hours, and the enameling temperature precisely maintained between 820 and 950 degrees Celsius. The base enamel undergoes 1 to 2 rounds of spraying, while the surface enamel receives 4 to 6 treatments. This advanced process effectively eliminates internal stress generated in the composite enameling materials, making the enamel layer denser, free of bubbles, with a clean porcelain surface and reduced risk of chipping, significantly enhancing the valve's impact resistance and service life. Every imported glass-lined diaphragm valve undergoes multiple strict inspection procedures before leaving the factory, ensuring that all performance indicators meet or even exceed industry standards, delivering a product of卓越 quality and reliable performance.

Conclusion

Thanks to the numerous advantages mentioned above, the imported glass-lined diaphragm valve is widely used in many industrial fields such as chemical, petroleum, pharmaceutical, pesticide, and food industries. In the chemical industry, it precisely controls the flow of corrosive media; in the pharmaceutical field, it ensures the hygiene, safety, and purity requirements of fluid transportation during drug production; in the food industry, it meets strict standards for controlling food raw materials and finished product fluids.
