Shanghai Liangda Valve Factory is a professional manufacturer of butterfly valves, offering a wide range of high-quality products designed for various industrial applications. A butterfly valve is a type of flow control device that uses a circular disc as the closing element, which rotates around a central shaft to open, close, or regulate the flow of fluid in a pipeline. Known for its simple structure, compact size, lightweight design, and low material consumption, the butterfly valve is an efficient and cost-effective solution for many piping systems.
In addition to its structural advantages, the butterfly valve provides excellent flow regulation and tight shut-off capabilities, making it suitable for both large and medium-sized pipelines. It is especially popular in low-pressure environments where ease of operation, quick switching, and minimal driving torque are essential. Over the years, advancements in materials such as anti-corrosive synthetic rubber and polytetrafluoroethylene (PTFE) have significantly improved the performance and durability of butterfly valves, allowing them to adapt to a wider range of working conditions.
In recent years, metal-sealed butterfly valves have gained popularity due to their enhanced resistance to high temperatures, low temperatures, corrosion, and erosion. These valves are now widely used in harsh environments and have begun to replace traditional globe valves, gate valves, and ball valves in many applications. Their reliable sealing performance and long service life make them a preferred choice in critical industrial systems.
The company offers a comprehensive range of butterfly valve products, including soft-seated, triple eccentric multi-layer hard-seated, elastic hard-seated, ventilation, American standard, telescopic, and sanitary butterfly valves. These valves are available in a variety of pressure ratings, including PN1.0–4.0MPa, ANSI CLASS 150–300LB, and JIS10–20K, with nominal diameters ranging from DN40 to DN2000. They can be connected via flange, clamp, butt weld, or lug connections, and are suitable for operating temperatures from -196°C to 700°C. The valves are available in multiple drive modes, including manual, worm gear, pneumatic, electric, hydraulic, gas-liquid linkage, and electro-hydraulic linkage. The valve bodies are made from a range of materials such as HT200, WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), and Ti, ensuring compatibility with different media and environments.
