Gas butterfly valve is a kind of gas equipment, and the valve body material is HP-b 59-1 copper. It turns on and off the gas by rotating the valve handle and is commonly used in both residential and industrial gas systems. The design of the disc handle gas valve is generally simple and easy to operate. When using the disc handle gas valve, it is necessary to ensure that it is installed correctly and perform regular maintenance to ensure safety.

The main body material of the gas butterfly valve is made of high-quality brass in line with the national standard (brand number HPb59-1), ensuring the reliability of the material. The blank is formed by the forging process, with uniform tissue density and no defects such as sand holes. It is different from cast products and has a long service life. After the fine machining of the valve body and valve cover, it needs to be treated by the high-temperature annealing process, which can effectively remove the internal stress generated by the mechanical processing and improve the strength and corrosion resistance of the valve body. Through multiple type tests, it has been proven that the valves of the Dunyun brand have exceeded the requirements of the anti-torsion performance and anti-bending performance indicators specified in the national standard.

The gas butterfly valve is equipped with an O-shaped sealing ring made of ethylene propylene diene monomer (EPDM) rubber that can withstand high and low temperatures. It can be used for a long time in the working temperature range of -20°C to 80°C. The valve stem is processed from extruded brass rods in line with the national standard HPb59-1, and the sealing ball is treated by chromium plating on brass, with the advantages of maintaining a firm connection without leakage. Its excellent performance can be more prominently demonstrated in harsh use environments such as high and low temperatures, strong acids and alkalis, and oil stains. Sealed by the rubber sealing ring, the safety and reliability of the gas pipeline system are increased exponentially. It has independent intellectual property rights, making you feel more at ease when using it. Relying on precise manufacturing technology, it has better corrosion resistance and is safer to use.
