In 2018, the output of safety valves was 250,000 sets. The company has more than 500 sets of special equipment such as modern intelligent machining centers, CNC machine tools, and ordinary machine tools, as well as oversized vertical lathes with a maximum diameter of 3.5 meters. It has special equipments for physical and chemical tests of metal materials, mechanical properties and mechanical tests, ultrasonic thickness measurement, non-destructive testing, spectral analysis, metal heat treatment, safety valve full performance test center, spring tension and compression tests and other special equipment.

The company is a member of the China General Machinery Industry Association Valve Branch, a designated production unit of China National Chemical Equipment Corporation, and a safety valve production license issued by the Ministry of Machinery Industry. Passed ISO9001 international quality system certification, National Technical Supervision Bureau special equipment manufacturing license "TS" certification, US ASME certification, ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification, is a member of Sinopec Resources City, China National Petroleum Corporation The first-level supply network unit, the national power network network member plant, China Petroleum Energy No. 1 Network, the national torch plan project unit, and the major taxpayer.

The company's main products include safety valves, butterfly valves, ball valves, gate valves, globe valves and non-standard valves, with more than 2,000 specifications. Can be designed and manufactured according to ANSI, API, DIN, BS, JIS, GB standards. The main materials of the produced valves are WCB, WC1, WC6, WC9, ZGCr5Mo, ZG15Cr1Mo1V, CF8, CF8M, CF3, CF3M, 12CrMoV, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, etc .; the driving modes are manual, worm gear transmission, electric, pneumatic, hydraulic, electric －Hydraulic linkage, etc .; nominal diameter from DN10 ～ 3000 and 1/2 "～ 36"; working pressure from 0.6 ～ 42.0 Mpa and 150Lb ～ 2500 Lb; working temperature-196 ℃ ～ 700 ℃. Products are widely used in power stations, boilers, petroleum, chemical, urban construction, medicine, fertilizer, metallurgy, mining and other industries. Some products have replaced imports and are used in key equipment of national key engineering projects.

The company has always insisted on survival by quality and development by technology, and has now developed into a high-tech enterprise integrating research, development, manufacturing, testing and sales of industrial valves. The company's existing staff of more than 400 people, including more than 50 technical and management staff, specializing in valve design, technology, testing and service work. The company has a CAD workstation and a CAAP development center. The after-sales service center can perform dynamic simulation and design of the product to ensure that it meets the demanding working conditions.

The company introduced a new concept of valve manufacturing, that is, the process is highly flexible, complex, lean, networked, informatized, and intelligent in manufacturing and management processes. The company is mainly composed of two parts, namely production equipment (hardware facilities) and software supporting the company's management. The company has valve processing lines, painting lines, assembly lines, etc. The company's sales (including pre-sales, after-sales service), production, technology, finance, personnel, and other businesses have achieved computer network, information, and intelligent management. It is an intelligent network valve factory. Every corner of the factory is covered by a computer network, forming a huge information nervous system, which provides a reliable and effective means for issuing various instructions and timely feedback of various information. The entire production and management is a perfect combination of modern information technology (IT) and traditional manufacturing technology (MT), providing you with networked, informationized and intelligent industrial valves.
