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/gear/pneumatic or electric actuators could be chosen by needs.

     CHAODA根据调研国内外的黑水,灰水调节阀的优势与缺点,深入研究黑水,灰水,灰浆,煤渣等工况条件,结合 CHAODA多年来研制生产黑水,灰水专用阀门的经验积累,成功研制开发了用于煤化工行业的黑水,灰水调节阀,申请了国家发明专利。Black Water used control valve主要用于煤化工,煤制油行业的气化炉装置,具有防共振,旋涡,硬裂,闪蒸,冲刷,气蚀等优点。独特的流体结构设计,选用特殊工艺, material配方和气动执行机构,使Black Water used control valve的性能更加稳定可靠。阀体材质可选用WCB,WC6-12,304,316L,双相钢,特种 material等。阀体可选择锻造或铸造。此阀完全可以替代国外的黑水,灰水调节阀。

After carrying out a research on the advantages & disadvantages of both dometic and international black & gray water used control valve, and also a study on the working condition of Black, Grey water, Slurry, Coal slag and etc, CHAODA Valves Group successfully developed the Gray & Black used control valve for coal chemical industry with its many years' experience in this area and was also awarded the national invention patent. Black water used control valve is mainly used on the coal gasifier of coal chemical & coal-to-oil industry with the advantages of anti-resonance,vortec,crack,flash,scouring,cavitation and etc. Unique fluidic structure together with special technic, material choosing and pneumatic actuation results in a reliable sealing performance of Black water used control valve. Various material could be chosen for body such as WCB, WC6-12, 301, 316L, Stainless steel, Special material and so on. Both forged or casting could be manufactured. The black water used control valve could be able to replace imported valve competely.
