    Development History of Butterfly Valve

    Butterfly valve developing history In the 1930s, the United States invented butterfly valves. This valve has a small operating torque, a small installation space and a light weight. Taking DN1000 as an example, the butterfly valve is about 2T, but the gate valve is as heavy as 3.5T. The butterfly valve is easy to combine with various driving devices, and has good durability and reliability. The relationship between the opening of the butterfly valve and the flow rate changes substantially linearly. If used to control flow, its flow characteristics are also closely related to the flow resistance of the piping. For example, if the diameters, forms, etc. of the two…

    What is the sanitary butterfly valve? Sanitary butterfly valve, also called hygienic butterfly valve, is a type of flow control device. It is  a form of Butterfly Valves whose valve body, valve disc, and other components are fabricated out of stainless steel. Sanitary butterfly valves are used to make a fluid start or stop flowing through a section of pipe for these devices in applications such as food and beverage processing, personal care, biomedical, or pharmaceutical industries. Type: Butterfly ValveReference No.: AV-1Sizes: 1″ – 4″End Types: Tri-Clamp, Pull HandleGrades: 304 – 316LOperation: Manual, Pneumatic Adamant Valves sanitary butterfly valves uses: AV-1 series stainless steel sanitary butterfly valves are widely used to the petroleum, metallurgy, plumbing, food, bio-pharmaceutical…

    3 Types of Sanitary Butterfly Valves

    A Quick Look at These Three Types of Sanitary Butterfly Valve. Sanitary Butt Welded Butterfly Valve, Sanitary Thread Butterfly Valves and Sanitary Flange Butterfly Valves.   Sanitary Butt Welded Butterfly Valve The Sanitary Butt Welded Butterfly Valves are triple offset structure and suitable for high temperature, high pressure, corrosion, etc. Its are quarter-turn valves which are used for isolating or regulating flow. They are favored for being lighter in weight, requiring less support and are suitable for water and gas, which makes them useful across industrial, mining and power applications. The butt-weld butterfly valve has various advantages such as good sealing performance, convenient operation, and quick opening and closing. They have no flanges, making…

    Sanitary Valve: Pneumatic Butterfly Valve

    The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. It uses a circular disc that rotates with the valve stem as a shutter to achieve the activation action. These valves are mainly used as shut-off valves, and can also be designed to have adjustment or section valve and adjustment functions. At present, butterfly valves are used more and more on low-pressure large and medium-diameter pipes. Pneumatic butterfly valves are classified into stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, and carbon steel pneumatic butterfly valve. The main advantages of the valve are simple structure, small size and light weight,…

    Sanitary Butterfly Valves Basics

    A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. The opening and closing member of a sanitary butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the sanitary valve body to achieve the purpose of opening, closing and regulating. Full opening to full closure of a butterfly valve is usually less than 900. The butterfly valve and butterfly rod themselves don’t have self-locking capabilities. In order to position the butterfly plate, a worm-wheel reducer needs to be installed on the valve rod. Using a worm-wheel reducer not only makes the butterfly…
