在阀门制造的广袤领域中，良工阀门宛如一颗璀璨明星，闪耀着历经岁月沉淀的光芒。自 1946 年创立以来，良工阀门便踏上了一段波澜壮阔的征程，用七十余载的坚守与创新，书写着阀门行业的传奇篇章。​

In the vast field of valve manufacturing, Lianggong Valve is like a shining star, shining with the light accumulated over time. Since its establishment in 1946, Lianggong Valve has embarked on a magnificent journey, writing a legendary chapter in the valve industry with more than 70 years of perseverance and innovation. ​

建厂初期，在旧上海复杂的经济环境下，良工阀门凭借卓越的品质与不懈的努力，迅速崭露头角，成为民族工业的杰出代表。新中国成立后，良工阀门更是积极响应国家号召，全身心投入到社会主义建设的浪潮之中。彼时，国内工业阀门领域一片荒芜，良工阀门勇挑重担，参与了工业阀门自力更生、自主生产的全过程，填补了诸多空白。1952 年公私合营后，良工阀门为石油机械工业配套设计、制造的各种铸钢阀门和采油树，广泛应用于玉门、大庆等油田以及新建的国家重大石化项目，为我国石油工业的发展奠定了坚实基础。​

In the early days of its establishment, in the complex economic environment of old Shanghai, Lianggong Valve quickly emerged as an outstanding representative of national industry with its excellent quality and unremitting efforts. After the establishment of the People's Republic of China, Lianggong Valve actively responded to the national call and devoted itself wholeheartedly to the wave of socialist construction. At that time, the domestic industrial valve field was barren, and Lianggong Valve bravely took on the heavy responsibility and participated in the entire process of self-reliance and independent production of industrial valves, filling many gaps. After the public-private partnership in 1952, Lianggong Valve designed and manufactured various cast steel valves and Christmas trees for the petroleum machinery industry, which were widely used in oil fields such as Yumen and Daqing, as well as newly built national major petrochemical projects, laying a solid foundation for the development of China's petroleum industry. ​

七十多年来，良工阀门始终秉持 “质良工精” 的理念，将匠心融入每一个阀门的生产环节。从最初的简单阀门制造，到如今能够生产涵盖闸阀、止回阀、电站阀、球阀、截止阀等在内的 150 多种型号、1000 多个规格的产品，良工阀门不断突破技术瓶颈，提升产品质量。在研发过程中，良工阀门汇聚了行业内顶尖的技术人才，组建了专业的研发团队，深入研究市场需求与行业发展趋势，持续投入大量资源进行技术创新。通过引进国际先进的生产设备与工艺，结合自身丰富的生产经验，良工阀门生产的阀门在性能、可靠性和耐用性方面均达到了国际领先水平。​

For over 70 years, Lianggong Valve has always adhered to the concept of "quality and precision", integrating craftsmanship into every production process of valves. From the initial simple valve manufacturing to now being able to produce over 150 models and 1000 specifications of products including gate valves, check valves, power station valves, ball valves, globe valves, etc., Lianggong Valve continuously breaks through technical bottlenecks and improves product quality. During the research and development process, Lianggong Valve has gathered top technical talents in the industry, formed a professional R&D team, conducted in-depth research on market demand and industry development trends, and continuously invested a large amount of resources in technological innovation. By introducing internationally advanced production equipment and processes, combined with its rich production experience, Lianggong Valve's valves have reached the international leading level in terms of performance, reliability, and durability. ​

良工阀门的产品广泛应用于电力、石油、化工、冶金、建筑、制药、造纸、煤矿、水泥等多个关键领域。在电站项目中，良工阀门的高温高压双自密封闸阀、电站阀等产品，凭借其卓越的耐高温、高压性能，以及精准的流量控制能力，保障了电站设备的稳定运行；在石油化工领域，其球阀、蝶阀等产品，具备出色的耐腐蚀性能，能够适应复杂恶劣的化学介质环境，有效确保了管道系统的安全与畅通；在建筑行业，良工阀门的各类水阀产品，以其良好的密封性和便捷的操作性能，为建筑物的给排水系统提供了可靠保障。​

Lianggong Valve's products are widely used in key fields such as power, petroleum, chemical, metallurgy, construction, pharmaceuticals, papermaking, coal mining, cement, etc. In power station projects, Lianggong Valve's high-temperature and high-pressure double self sealing gate valves, power station valves, and other products, with their excellent high-temperature and high-pressure resistance, as well as precise flow control capabilities, ensure the stable operation of power station equipment; In the field of petrochemicals, its ball valves, butterfly valves and other products have excellent corrosion resistance and can adapt to complex and harsh chemical media environments, effectively ensuring the safety and smoothness of pipeline systems; In the construction industry, various water valve products of Lianggong Valve provide reliable guarantee for the water supply and drainage system of buildings with their good sealing and convenient operation performance. ​

凭借着过硬的产品质量与完善的服务体系，良工阀门在国内外市场赢得了极高的声誉。公司先后荣获中华人民共和国特种设备生产许可证 “TS”、ISO14001:2004 环境管理体系认证证书、GB/T28001 - 2001 职业健康安全管理体系认证证书等众多权威认证，成为中国化工部定点单位、中国电力设备配件网成员企业、ISO9001:2000 质量体系认证企业、中国石油和石油化工设备会员单位等。这些荣誉不仅是对良工阀门过去努力的肯定，更是激励其不断前行的动力源泉。​

With excellent product quality and a comprehensive service system, Lianggong Valve has won a high reputation in both domestic and international markets. The company has successively won numerous authoritative certifications such as the Special Equipment Production License "TS" of the People's Republic of China, ISO14001:2004 Environmental Management System Certification, GB/T28001-2001 Occupational Health and Safety Management System Certification, and has become a designated unit of the Ministry of Chemical Industry of China, a member enterprise of the China Power Equipment Parts Network ISO9001: 2000 Quality System Certification Enterprise, Member Unit of China Petroleum and Petrochemical Equipment, etc. These honors are not only a recognition of Lianggong Valve's past efforts, but also a source of motivation for its continuous progress. ​
