An important actuator in industrial automation control systems, powered by electrical energy, automatically adjusts valve opening by receiving control signals output by the control system,So as to control the flow, Pressure, temperature and other parameters of the fluid in the pipeline,For different working environments, electric control valves have multiple protection levels to choose from, which can adapt to harsh environments such as humidity, dust, corrosion, etc; In flammable and explosive places, there are corresponding explosion-proof products to ensure safe operation. The electric actuator adopts mature technology and high-quality components, with high reliability and stability, and a relatively long maintenance cycle, reducing production interruptions caused by valve failures.


Company Profile
Shanghai Power Station Valve Factory Co., Ltd. was founded in 1966 and is located in Qingpu Park, Zhangjiang High tech Industrial Development Zone, Shanghai. The company was formerly known as Shanghai Power Station Valve Factory. After more than 50 years of entrepreneurship, creation, and innovation, the SDF brand is now a professional factory designated by the Ministry of Machinery and the State Power Corporation to produce high-temperature and high-pressure power station valves. It is a recommended enterprise for the main auxiliary equipment of 660MW and 1000MW thermal power units by the Power Planning and Design Institute, as well as recommended enterprises for the main auxiliary equipment of 660MW and 1000MW thermal power units by Huaneng, Huadian, Datang, State Power Investment, State Energy Investment, and various local power groups. It is also a member unit of the China Petroleum and Sinopec Equipment Industry Association.
The company has complete production equipment and sophisticated testing methods. The company's new factory covers an area of 73336 square meters, with a total investment of several billion yuan. The company has introduced major equipment such as "Olympus" optical emission direct reading spectrometer, ray flaw detection room, ultrasonic flaw detector, DP600 sealing surface plasma spray welding machine, 1800t high pressure large diameter valve Pressure testing machine, DN4000 CNC vertical machining machine tool, machining center, etc., so that the product processing and manufacturing capacity and testing level have been rapidly improved and improved. At present, the production capacity of 800000 sets of forged steel valves per year has been formed.
The company has passed various qualification certificates such as the three system certification (quality, environment, occupational health and safety management system), A1, A2, B level (gate valve, globe valve, check valve, regulating valve, ball valve, butterfly valve, ultra-low temperature valve, etc.) of special equipment production license qualification, API certification, EU CE certification, etc. earlier in the same industry. The company has modern testing methods including mechanical properties, spectroscopy, metallography, PT, UT, RT, MT, etc. The factory and type testing capabilities of the valve include high and low pressure water or gas testing, high and low temperature valve testing, valve fire testing, valve low leakage testing, valve switch cycle life, valve flow measurement testing, valve vacuum testing, etc. The valve testing process has obtained third-party certification certificates.
The main products produced include gate valves, globe valves, check valves, ball valves, butterfly valves, regulating valves, drain valves, instrument valves, etc; Mainly covering industries such as electricity, chemical (coal chemical/refining/fine chemical), natural gas, petrochemicals, metallurgy, nuclear power, etc. More than 2000 types and specifications of valves; Valve body materials include carbon steel, stainless steel, alloy steel, low-temperature steel, and various special materials; Pressure: 1.6MPa~80.0MPa, Class150~Class4500; The nominal Size ranges from DN10mm to 6000mm, and the temperature ranges from -196 ℃ to 1100 ℃. The driving modes include manual, gear transmission, electric, pneumatic, and hydraulic; The product adopts standards such as NB/T, GB, JB, ANSI, API, JIS, BS, DIN, GOST, NF, etc. While the company attaches great importance to domestic market sales, its products are also exported to countries such as Europe, America, Pakistan, India, Japan, Iran, Indonesia, Bangladesh, the Philippines, and Malaysia.
Adhering to the core concept of "integrity, innovation, exploration, and win-win", Shanghai Power Station Valve Factory Co., Ltd. is committed to researching valve technology for harsh working conditions, providing customers with systematic valve application solutions, and building a national brand of industrial valves!
