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, and lightweight design, this valve is not only cost-effective but also efficient in terms of material usage and installation space.
Butterfly valves are widely used in low-pressure environments due to their excellent flow regulation capabilities and reliable sealing performance. Over the years, advancements in materials such as anti-corrosive synthetic rubber and PTFE (polytetrafluoroethylene) have significantly enhanced the durability and adaptability of these valves, allowing them to perform well under different operating conditions.
In recent years, metal-sealed butterfly valves have gained popularity due to their improved resistance to high temperatures, low temperatures, corrosion, and erosion. The use of high-strength alloy materials has further expanded their application range, making them a preferred choice in many industries, often replacing traditional globe, gate, and ball valves.
The structural advantages of butterfly valves include a simple design, quick operation, 90° rotation movement, and low driving torque. They are ideal for cutting off, connecting, and regulating media in pipelines, with excellent fluid control and sealing properties.
Our company offers a comprehensive range of butterfly valves, including soft-seated, triple-offset multi-layer hard-seated, elastic hard-seated, ventilation, American standard, telescopic, and sanitary types. These valves are available in various pressure ratings (PN1.0–4.0MPa, ANSI CLASS 150–300LB, JIS10–20K) and nominal diameters (DN40–2000). Connection types include flange, clamp, butt weld, and lug connections. They operate within a temperature range of -196°C to 700°C and can be manually operated or driven by worm gear, pneumatic, electric, hydraulic, gas-liquid linkage, or electro-hydraulic systems.
Materials used for the valve body include HT200, WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), and Ti, ensuring versatility and reliability across different applications.
