在閥門制造的廣袤領域中，良工閥門宛如一顆璀璨明星，閃耀著歷經歲月沉淀的光芒。自 1946 年創立以來，良工閥門便踏上了一段波瀾壯闊的征程，用七十余載的堅守與創新，書寫著閥門行業的傳奇篇章。?

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. ?

建廠初期，在舊上海復雜的經濟環境下，良工閥門憑借卓越的品質與不懈的努力，迅速嶄露頭角，成為民族工業的杰出代表。新中國成立后，良工閥門更是積極響應國家號召，全身心投入到社會主義建設的浪潮之中。彼時，國內工業閥門領域一片荒蕪，良工閥門勇挑重擔，參與了工業閥門自力更生、自主生產的全過程，填補了諸多空白。1952 年公私合營后，良工閥門為石油機械工業配套設計、制造的各種鑄鋼閥門和采油樹，廣泛應用于玉門、大慶等油田以及新建的國家重大石化項目，為我國石油工業的發展奠定了堅實基礎。?

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. ?

七十多年來，良工閥門始終秉持 “質良工精” 的理念，將匠心融入每一個閥門的生產環節。從最初的簡單閥門制造，到如今能夠生產涵蓋閘閥、止回閥、電站閥、球閥、截止閥等在內的 150 多種型號、1000 多個規格的產品，良工閥門不斷突破技術瓶頸，提升產品質量。在研發過程中，良工閥門匯聚了行業內頂尖的技術人才，組建了專業的研發團隊，深入研究市場需求與行業發展趨勢，持續投入大量資源進行技術創新。通過引進國際先進的生產設備與工藝，結合自身豐富的生產經驗，良工閥門生產的閥門在性能、可靠性和耐用性方面均達到了國際領先水平。?

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. ?
