Yongyi Valve Group Co., Ltd. was established in 1984. The industrial park covers an area of ​​90,000 square meters. The company has more than 500 special equipment such as modern intelligent machining center, (robot) truss robot, CNC machine tools, ordinary machine tools, etc. and has an extra-large vertical lathe with a maximum machining diameter of 3.5 meters. It has special equipment such as physical and chemical tests of metal materials, mechanical ability tests, ultrasonic thickness measurement, non-destructive flaw detection, spectral analysis, metal heat treatment, safety valve full performance testing center, spring tension and pressure test.

The enterprise is a member unit of the Valve Branch of the China General Machinery Industry Association, a designated production unit of the China Chemical Equipment Corporation, and a safety valve production license issued by the Ministry of Machinery Industry. Passed ISO9001 international quality system certification, the "TS" certification of the special equipment manufacturing license of the National Technical Supervision Bureau, the US ASME certification certificate, ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. He is a member of Sinopec's resource market and China National Petroleum and Natural Gas Group First-level supply network unit, member factory of the National Power Network, China Petroleum and Energy Network, National Torch Plan project unit, and a large taxpayer.

The company mainly produces more than a dozen varieties, including safety valves, butterfly valves, ball valves, gate valves, shut-off valves and non-standard valves, with more than two thousand specifications. It can be designed and manufactured according to ANSI, API, DIN, BS, JIS, and GB standards. The main materials of the produced valves include WCB, WC1, WC6, WC9, ZGCr5Mo, ZG15Cr1Mo1V, CF8, CF8M, CF3, CF3M, 12CrMoV, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, etc.; the driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electric -Liquid linkage, etc.; nominal diameters range from DN10 to 3000 and 1/2" to 36"; working pressures range from 0.6 to 42.0Mpa and 150Lb to 2500Lb; working temperature -196℃ to 700℃. The products are widely used in power stations, boilers, petroleum, chemical industry, urban construction, medicine, fertilizers, metallurgy, mining and other industries. Some products have been replaced by imports and are used in key equipment for national key engineering projects.

The company has always insisted on survival by quality and development by technology. It has now developed into a high-tech enterprise integrating the research, development, manufacturing, testing and sales of industrial valves. The company currently has more than 400 employees, including more than 50 technical staff and management staff, specializing in valve design, process, testing and service. The company has a CAD workstation and a CAAP development center. The after-sales service center can conduct dynamic simulation and design of products to ensure that they meet the demanding working conditions.

The company has introduced a new concept of valve manufacturing, namely, the processing process is highly flexible, composite, lean, and networking, informatization and intelligence of manufacturing and management processes. The company is mainly composed of two parts, namely production equipment (hardware facilities) and software that supports the company's management. The company has built valve processing assembly lines, coating operation lines, assembly operation lines, etc. The company's sales (including pre-sales and after-sales services), production, technology, finance, personnel and other businesses have realized computer networking, informatization and intelligent management, and is an intelligent network valve factory. Every corner of the factory is covered by computer networks, forming a huge information nervous system, providing reliable and effective means for issuing various instructions and timely feedback of various information. The entire production and management are a perfect combination of modern information technology (IT) and traditional manufacturing technology (MT), providing you with networked, informative and intelligent industrial valves.
