Where are butterfly valves used?
Where are butterfly valves used?
Butterfly valves are used for applications that require handling large volume capacities. It can be used for flow control and regulation and on/off service. Recent developments have permitted this type of valve to throttle more accurately and perform well in high-temperature and high-pressure applications.
How does a butterfly valve work?
Butterfly valves operate like other quarter turn valves. The butterfly is mounted on a rod and when the valve is closed it blocks passage of fluid. When the valve is fully open, the metal disc or butterfly moves a quarter turn. The passageway is unrestricted allowing fluids or air to pass.
Where are ball valves used?
Ball valve is the most used fluid shutoff valve in upstream oil and gas production facilities, both onshore and offshore. They are also used in fuel gas systems feeding furnaces. Plug valves present the following advantages: Resistance to high pressure.
Where are gate valves used?
Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Non-rising stem gate valves are very popular on ships, in underground applications, or where vertical space is limited because they don’t take up extra space.
Do Butterfly Valves have a flow direction?
The butterfly valves are bi-directional but do have a preferred flow direction. It’s however strongly recommended to install the valves in the preferred flow direction, as it will extend the valve’s life span and will also lower the operating torque.
What is a seated gate valve?
Resilient seat gate valves are gate valves with an elastomer lined wedge. They are especially used for waste water, drinking water supply and irrigation.
What is gate valve function?
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance.
