The purpose and use of both gate and butterfly valves are same.
The difference between the both valves lies in shape, size and operation.
Butterfly valves are lighter than gate valves, so for the big sizes it is convenient to install and operate butterfly valve because it is lighter and compact in compare to gate valves.
Gate Valve: This type of valve actually functions like a gate, a simple open/close movement, with the disc perpendicular to the direction of the flow. It's available different kinds of designs like Knife, Wedge, Pipeline slab and Parallel Slides designs. We can also use it myriad of purposes. Discharge is usually complete with no residues left standing in the pipeline.
Butterfly Valve: Its designs available in the form of a disc or double or triple offset shafts that operate perpendicular to the flow direction. Such valves can easily control flow but do leave some residual material in the pipes. Well! I think you can go at clarksol.com to explore more stuff related to valves and pumps.
what is differnce between gate and globe valve????
1- gate valve used for complete closed or open , but butterfly valve used for partial open and closed
2- gate valve used for maintains purpose but butterfly valve can used for controlling fluid or regulating the flow
A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The Gate valves are used when a straight-line flow of fluid and minimum restriction is desired. A butterfly valve is a valve which can be used for isolating or regulating flow These valves can be used effectively in freshwater, saltwater, lube oil, and chill water systems aboard ship. The butterfly valve is light in weight, relatively small, relatively quick-acting, provides positive shut-off, and can be used for throttling. The butterfly valve has a body, a resilient seat, a butterfly disk, a stem, packing, a notched positioning plate, and a handle.
