Tieling Valve Manufacturing Co., the company formerly known as Liaoning Tieling valve factory. Is one of the China largest professional valve manufacturing enterprise, is the two large state enterprises, the plant since 1935 has been 70 years history of production and operation. China is ranked one of the top 500 largest industrial enterprises in machinery, Northeastern University, science research, production base, is also the national standard drafting units multiple valve. The company technology center was named the provincial enterprise technology center, is the State Science and Technology Commission named advanced high-tech enterprises. Is Liaoning province Shou contract, re credit enterprises, China General Machinery Industry Association vice president of units valves Branch length. Is China water industry products technology assessment of choice for enterprises, the Ministry of construction, national power company, China Water Association recommended products enterprises. The company covers an area of 200000 square meters, construction area of 100000 square meters, is located in Tieling City, Liaoning Province, is 47 kilometres north of Shenyang. The company's total assets of 200000000 yuan, the existing staff of 1280 people, among them (professor level senior engineer 11 people, engineers) 67. The main production equipment: 8 tons, 5 tons of the cupola of the two, 5 ton electric furnace two, equipped with an annual output of 5000 tons casting resin sand molding production line equipment such as casting, has 8 meters, 5 meters vertical lathe, boring machine, Germany BFP160 CNC machine, plasma cutting machine, cutting plate machine mechanical equipment 50mm thousands of stations, metering, physicochemical, testing equipment. Production of gray cast iron, ductile iron, carbon steel, stainless steel valves and all kinds of steel plate welded valve, the annual production capacity of 20000 tons. Tieling valve factory in 1995 took the lead in the China valve industry by the Norway classification society DNV company ISO9001 quality system certification, the same year and made the civil nuclear pressure equipment design qualification issued by the State Nuclear Safety Bureau license and manufacturing license. Plant technology center was named the provincial technology center, has built the country's largest valve simulation condition dynamic test base, with continuous development of new products and developed to meet the special requirements of users of valve products capacity and conditions. Our factory has obtained national patents twenty, the title of quality products and technology achievement award thirty items, of which three national new product award. The main production of butterfly valve, gate valve, check valve, regulating valve, exhaust valve, gate valve, power plant and other 20 series. Nominal pressure is from 0.01MPa to 32 MPa; nominal diameter up to 6000mm; suitable medium: water, wastewater, high temperature furnace gas, gas, steam and acid, alkali, salt liquid; suitable temperature of - 196 to + 880 DEG C; drive a manual, electric, pneumatic, hydraulic and other. Products are widely used in city water supply and drainage, gas, electric power, metallurgy, petrochemical and other industries. As early as 1958 developed the first domestic DN3000mm gas valve, in 1965 developed the DN500mm wafer butterfly for Fushun oil two plants, in 1984 for the localization of the valve supporting 300MW and 600MW thermal power unit, developed DN3000mm butterfly valve used in Kubota technology introduced from Japan, Anhui Pingwei Power plant. In 1990 DN1600 has been developed for the vacuum butterfly valve in Zouxian Power Plant, Shanghai Waigaoqiao Power Plant, in 1992 for the Shanghai sewerage project developed DN2000mm hydraulic main valve, 3.5m * 4.0m gate, Fushun Mining Group shale oil refinery by the national development and Reform Commission as a national oil shale comprehensive utilization demonstration base, and plans to shale oil production scale development to 3000000 tons / year level. In the pipe network of shale oil refinery, the large-diameter gas valve and gas valve by our factory according to the working requirement of special offer, since 1991 has run stable work, the specific requirements of the technical performance of gas valve and gas valve can reach the oil shale retorting refinery. Tieling valve factory is a flag China valve industry, valve industry is a bellwether of China, is Chinese national industry transition from the liberation to the typical representative of the modern system of socialist market economy in the state-owned enterprises. Since foundation of more than 70 years, always is in carry out to the quality of survival, growing strategic thinking to the credibility of development in. Today Tieling valve factory is still based on product quality to win credibility, open up the market to product technology, seek the development based on product innovation. For our country and the world of key projects for many years to provide the high quality valve products in large quantities, has set an example for the development of the valve industry in china. The company's products are widely used in thermal power plants, hydropower station, nuclear power station, city water supply, sewage treatment, lead, gas, metallurgy, mine, petroleum, chemical and other industries.

I have a wide range of products, complete specifications. The main production of butterfly valve, gate valve, check valve, globe valve, regulating valve, exhaust valve, ball valve, plug valve, gate, expansion joint and piping accessories, complete valve pipe fittings group and other 12 categories, more than 500 models, in tens of thousands of specifications of valve products, suitable medium water, sewage, sea water, air the high temperature furnace, gas, gas, steam and various liquids such as acid-base salt, apply pressure 1X10-7 (absolute pressure) for -2.5MPa, temperature of -196 degrees Celsius -680 degrees Celsius, the largest nominal diameter up to 6 meters. The drive a manual, electric, pneumatic, hydraulic, electro-hydraulic linkage, etc.. These products, widely used in hydropower station, nuclear power plant, power plant, water plant, sewage treatment plant, Steel Corp and aerospace, metallurgy, coal, petroleum, chemical industry, city high-rise building, mining, water conservancy and other industries.
