在現代工業流體控制系統中，閥門作為關鍵的調節樞紐，其品質直接關系到整個生產系統的安全與穩定。以“上海良工閥門廠有限公司”為代表的“良工”品牌，憑借其深厚的歷史積淀與精湛的制造工藝，在業內樹立了卓越的口碑。

In modern industrial fluid control systems, valves serve as key regulating hubs, and their quality directly affects the safety and stability of the entire production system. The "Lianggong" brand, represented by "Shanghai Lianggong Valve Factory Co., Ltd.", has established an excellent reputation in the industry with its profound historical accumulation and exquisite manufacturing technology.

追溯其發展歷程，該品牌前身可至1946年創建的“良工機器廠”，歷經數十載發展，不僅開創了我國自制高壓鑄鋼閥門的歷史，更曾為我國第一座核電站（秦山核電站）及大慶油田等國家級重大工程提供核心閥門設備，展現出強大的技術實力與國企擔當。

Tracing its development history, the brand's predecessor can be traced back to the "Lianggong Machinery Factory" founded in 1946. After decades of development, it not only pioneered the history of self-made high-pressure cast steel valves in China, but also provided core valve equipment for China's first nuclear power plant (Qinshan Nuclear Power Plant) and national level major projects such as Daqing Oilfield, demonstrating strong technical strength and state-owned enterprise responsibility.

在產品矩陣方面，良工閥門覆蓋了多種嚴苛工況需求。其主打的不銹鋼截止閥系列（如J41W-16P），憑借優異的耐腐蝕性與潔凈度，廣泛應用于食品醫藥純水、化工弱酸介質及市政供水等管路場景；針對高溫高壓或強腐蝕的極端環境，良工推出了采用鉻鉬鋼或316不銹鋼材質的電動法蘭截止閥（如J941H-40I），這類閥門結構緊湊、密封可靠，且非常適合對流量進行精準調節。

In terms of product matrix, Lianggong valves cover a variety of harsh operating conditions. Its flagship stainless steel globe valve series (such as J41W-16P), with excellent corrosion resistance and cleanliness, is widely used in pipeline scenarios such as food, medicine, pure water, chemical weak acid media, and municipal water supply; For extreme environments with high temperature, high pressure, or strong corrosion, Lianggong has launched electric flange globe valves (such as J941H-40I) made of chromium molybdenum steel or 316 stainless steel materials. These valves have a compact structure, reliable sealing, and are very suitable for precise flow regulation.

此外，依托杭州等地的專業生產基地，良工還研發了無需外接電源氣源的自力式蒸汽減壓閥，利用介質自身的壓力反饋實現自動調壓，廣泛服務于石油、化工、冶金及民用建筑等領域，彰顯了其在自動化控制閥門領域的全面布局。

In addition, relying on professional production bases in Hangzhou and other places, Lianggong has also developed a self operated steam pressure reducing valve that does not require an external power source. It uses the pressure feedback of the medium itself to achieve automatic pressure regulation and is widely used in the fields of petroleum, chemical, metallurgy, and civil construction, demonstrating its comprehensive layout in the field of automated control valves.
