CQ47 long distance pipeline ball valve

Product characteristics

This series ball valve is according to the needs of users, in order to meet the requirements of anti-vulcanization stress cracking in the vulcanization environment, we from the design, material selection, manufacturing, testing, surface treatment and painting are strictly in accordance with the American Institute of Corrosion Engineers NACE standards.
This series of ball valves is not only a wide range of materials and internal materials are nickel-plated or 316 material, the sealing ring is made of special polymer material. The valve is not only anti-corrosion, anti-vulcanization ability is strong, fire prevention, anti-static, good sealing performance, suitable for a wide range of pressure and temperature, full diameter and reduced diameter complete, and can be equipped with a variety of driving devices, is the chemical industry, petroleum refining, natural gas extraction and transportation system ideal valve choice.
