By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs. 

    浙江 CHAODA VALVES股份有限公司研制的灰水黑水灰浆及煤浆用特种金属硬密封球阀被列为“2008~2009年国家火炬计划项目”。国家火炬计划中认定一批重点火炬计划项目。这些项目具有我国自主知识产权,技术水平在中国阀门行业中居领先地位,项目市场前景好,产业规模大,有较强的市场竞争能力和较大的市场覆盖面,是中国重点发展的高新技术产业。灰水黑水灰浆及煤浆用特种金属硬密封球阀被列为国家火炬计划项目,对推动 CHAODA VALVES公司产品品牌影响力,提升该公司产品往国际高端方向发展起到了很积极的作用。

The Gray, Black water, Mortar & Coal slurry used metal to metal sealed ball valve is listed as the "National torch project of year 2008~2009". The products listed as the national torch project which would be national high tech industry should have following features: With independent intellectual property; Leading technology position in China valve industry; Good market prospect; Big industrial scale, Strong competition and large market coverage.The honor of being listed as national torch project of Gray,Black water, Motar & Coal slurry metal to metal sealed ball valve would play a positive function in improving the influence of CHAODA brands and stepping into the international market. 

    灰水黑水灰浆及煤浆用特种金属硬密封球阀具有以下突出优点:针对工况介质易粘结的的特点,在阀座的密封面两侧设置了刮刀装置( CHAODA专利结构),在阀门启闭时能自动刮除粘结在球体密封面上的脏物,保持球体密封面的清洁,保证球体与阀座很好的贴合,使阀门始终具有良好的密封性能;采用自主研制的中频感应加热的火焰喷焊工艺,使球体,阀座的硬度达到HRC60以上,结合力高。研制了球体研磨设备,保证了密封性能。灰水黑水灰浆及煤浆用特种金属硬密封球阀用于启闭频繁(半个小时动作一次),启闭速度快(一般为3秒至10秒),高温,高压(一般采用Class600至Class900压力级),含有大量的固体硬颗粒的灰水,黑水,灰浆及煤浆等介质工况。产品密封性能好,密封可靠,使用寿命长。

The outstanding advantages of Gray, Black water, Motar & Coal Slurry used metal to metal sealed ball valve are: Owing to the characteristic that the medium is easy to be deposited on the valve, scraper-like structure(CHAODA'S Patent) has been provided for the seat ring area so that self-cleaning would be done for ball surface and thus to ensure the cleaness of sealing face and have a good sealing performance; Self-developed medium frequency heating flame spraying technology makes the hardness of ball & seat above HRC60 with good combining strength. Self developed ball grinding device ensures the sealing of ball. Grey, Black water, Motar & Coal Slurry used metal to metal sealing ball valve are suitable for working condition of frequent closing & opening (Half an hour once), quick closing to opening speed(3 to 10 seconds ), high temperature, high pressure(normally class 600 To class 900), containing massive particle with features of good sealing performance, reliable safety guarantee, long life span and etc.
