Severe Service Valves[INQ. NO. 1707M23] DaehanCVD is a company that produces valves used under unfavorable conditions by applying CVD coating technology, which is the original patent technology that chemically penetrates metallic materials into the parent metal. HVOF, spray and fusing process (Tungsten carbide coating, chrome carbide coating, Ni-Cr fusing) also can be applied to products depending on site environments. Valves manufactured by the company are super wearresistant special industrial valves for high temperature, high pressure (Max 4500Lbs) and malignant slurry used in extreme environments such as power plants, petroleum refineries, petrochemical plants, coal chemical plants, polysilicon factories, etc.
Existing valves have the problem of very short lifespan because of friction/abrasion by slurry, abrasion by flow velocity and corrosion and abrasion of contacted parts due to characteristics of their structures and materials.Worldclassvalvemanufacturers also have similar problems.
For this, DaehanCVD developed valves of ultra-high hardness wear-resistant material by applying penetration CVD coating technology, which has the patented hardness HV2200 (HRc84). When compared with existing global top valves, the company’s valves have a 2~3 times longer lifespan and notable price competitiveness. | Blog Magazine of korean-machinery, brands and Goods
