For corrosive liquids, Kunshan Lianggong's J41F4-16 and J41F46-16 fluorine lined globe valves perform outstandingly. Suitable for temperatures ranging from -50 to 150 ℃, it can be used in pipelines for various strong acids, alkalis, corrosive gases, and liquid media such as aqua regia and sulfuric acid. This series is lined with PTFE (F4) and can resist various highly corrosive media. The principle is to use fluorine lined materials to isolate the corrosive media from the valve substrate, ensuring stable operation of the valve in complex corrosive environments. ?

此外，良工的不銹鋼球閥也適用于水、溶劑、酸和天然氣等部分腐蝕性介質管路。不銹鋼材質耐蝕，球閥結構緊湊、流體阻力小、操作便捷，開閉只需旋轉 90°，便于遠程控制。?

In addition, Lianggong's stainless steel ball valves are also suitable for pipelines containing corrosive media such as water, solvents, acids, and natural gas. Stainless steel material is corrosion-resistant, and the ball valve has a compact structure, low fluid resistance, and easy operation. It only needs to be rotated 90 ° for opening and closing, making it convenient for remote control. ?

高粘度介質適配閥門?

Valve adapted for high viscosity media

一體式保溫球閥是良工適用于高粘度介質的代表。它保溫保冷性能佳，閥門通徑與管徑適配，能減少介質熱量損失，用于輸送常溫下易凝固的高粘度介質，如石油、化工等系統。其整體式結構讓閥門體積小、重量輕、無外漏、密封好，夾套采用焊接碳素鋼管，耐壓牢固。?

The integrated insulated ball valve is a representative of Lianggong's suitability for high viscosity media. It has excellent insulation and cooling performance, and the valve diameter is compatible with the pipe diameter, which can reduce the heat loss of the medium. It is used to transport high viscosity media that are prone to solidification at room temperature, such as petroleum, chemical and other systems. Its integral structure makes the valve small in size, light in weight, leak free, and well sealed. The jacket is made of welded carbon steel pipe, which is pressure resistant and firm. ?

江蘇良工牌電動 V 型調節球閥適用于高粘度、懸浮液、紙漿等含纖維介質場合。它與執行機構直連，結構緊湊、尺寸小、重量輕、阻力小且動作靈敏。V 型閥體設計，在小流量或高粘度時也能精確控制。閥座有軟、硬密封，關閉時 V 型缺口與閥座有楔形剪切作用，具有自潔功能，可防球芯卡死，適用于管線結垢或含纖維、顆粒固體的場合。

Jiangsu Lianggong brand electric V-shaped regulating ball valve is suitable for high viscosity, suspension, pulp and other fiber containing media applications. It is directly connected to the actuator, with a compact structure, small size, light weight, low resistance, and sensitive action. The V-shaped valve body design allows for precise control even at low flow rates or high viscosity. The valve seat has soft and hard seals, and when closed, the V-shaped notch has a wedge-shaped shear effect with the valve seat. It has self-cleaning function and can prevent the ball core from getting stuck. It is suitable for situations where pipelines are scaled or contain fiber or particle solids.
