Butterfly Valve Design List
Butterfly valves typically pivot on axes perpendicular to the direction of flow inside the flow chamber and are situated on a spindle that allows for flow in a single direction. They are frequently used as throttling devices, controlling the levels of flow in entirely closed, entirely open or partially open positions. Butterfly valve suppliers stock numerous closure types and body configurations, depending on the type of flow control needed and the design.
Butterfly valves are commonly composed of metals like cast iron, aluminum and stainless steel, but can also be made from various plastics. Butterfly valves are designed and sold in many diameters, resulting in different flow rates. Smaller butterfly valve assemblies may be used where space is limited. Butterfly valves are used in many food transporting and chemical plants where controllable product flow is required. Other specific applications include HVAC, petroleum recovery and industries that use high pressure water.
Butterfly valves are fairly simple in design. When prompted, the disc rotates and stands upright in the pipe, resting on a seal or gasket and forming a tight seat. The design offers many benefits. First of all, they generally have a long life cycle. Butterfly valves are easy to maintain, lightweight and compact and able to handle a wide range of temperatures.
These valves are also very reliable because of their tight shutoff, reducing the amount of leakage. These butterfly valves are categorized as rotary valves, which are generally recognized by the quarter turn that is used to move from the open to closed position and back again. This results in a lower surface friction, which means that these valves can be smaller than others and still operate efficiently.
Compared with ball valves, butterfly valves do not have pockets to trap fluids when the valve is in the closed position. A certain kind, flanged butterfly valves, can be mounted between flanges. Another, the lug butterfly valve, uses metal inserts that are attached to the valve's bolt holes. Using an independent set of bolts for each flange, this butterfly valve's assembly is fixed between two flanges. Finally, wafer butterfly valves are the cheapest and most popular type of butterfly valves because of their simplicity and ease of use.
