Zhejiang Dongsen Valve Co.,Ltd

Zhongcheng Valve Co., Ltd. was founded in 1998, is the largest valve manufacturers.'s Long-term commitment to the petroleum, petrochemical, natural gas, nuclear power, hydropower, thermal power and other fields of research and development of valves , and the heavy machinery and equipment package for domestic and foreign, is vice president of China Valve Association, China's valve members of the Committee of Experts, the National Standards drafting unit of the valve, known reputation for high quality. the company covers an area of more than 10,000 square meters a registered capital of 10.08 million yuan, the staff 102people, produces valves than 1,000 tons. After several decades of effort, the company has formed a knife gate valve, slurry valve,slide gate valve,ball valve, butterfly valve, globe valve, check valve, plug valves, control valves, etc. as the leading valve product system, with a caliber up to 60 "and the pressure up to 4500LB, using the temperature range of -196 ~ 750 ℃, covering carbon steel, low carbon steel, stainless steel, duplex stainless steel, high temperature alloys steel, MONEL, INCONEL, Hastelloy, titanium alloys and other materials. The valve structure, performance, quality has reached the advanced level of similar products at home and abroad, are widely recognized by domestic and international users. Company's engineers and technicians of all types, 10, can skillfully make use of CAD, three-dimensional graphics and limited source of analysis, design software, and with domestic and international customers, research institutes engaged in technical cooperation, the introduction and development of a number of new products, obtain more patent certificate. In addition, the company also has first-class processing and testing equipment, there are a variety of high-precision, large-scale machining center, CNC machine tools, and specialty-specific equipment, such as horizontal machining center, machining center, gantry processing center, large-scale Ball Lathe , horizontal boring and milling machine, etc.; equipped with PMI, tensile test, impact test, metallurgical microscope and other materials testing equipment, r-Ray, ultrasound, magnetic particle, liquid infiltration and other nondestructive testing methods, as well as three-dimensional measuring instrument, low-temperature test, fire test, low-leakage test, vacuum test, and other special test equipment; now under construction a valve cold and hot state test loop used to simulate the high and low temperature operating conditions of the valves tested. The company focus on the hardware infrastructure, while also focusing on quality management system and product certification, issued by DNV have obtained ISO9001, certificate, and received the American Petroleum Institute API6D, Lloyd's Register of API607 , the French classification society of the CE / PED and the National Nuclear Security Administration's nuclear pressure equipment design and manufacturing licenses, as well as national pressure piping components, the security certificate of registration (AZ). It is because the company has strong design and development capability, first-class processing and testing equipment, perfect quality management system, as well as the unity and coordination of the work team, which effectively guarantees the product performance, quality and delivery, has won the favor of customers. Today ZC valve has been widely used in domestic and international large-scale petroleum, chemical, electric power, iron and steel, shipbuilding, water treatment and other fields. We hope to work with national research institutes, national new and old customers work together to create a bright future!
