Lug Butterfly Valve Uses
A lug butterfly valve can assist a company in regulating the flow of substances through their system. Whether these particular substances happen to be gases or liquids, a company will need to have the ability to control where they go, and how much of them go to that place. Regulation is essential in systems of circulation, filtering, refining, or other types of production. A lug butterfly can provide the needed manipulation over the gas or a liquid as it moves through a pipeline.
A lug butterfly valve has a body with threaded inserts on the sides. This type of design allows for a lug butterfly valve to be installed into a system without the use of any nuts, although two sets of bolts are still necessary. The benefits of using this type of butterfly valve is that one side of the system of pipelines can be disconnected, even while the other side continues to operate normally. For companies that may need to change up their operation, or perform maintenance or cleaning procedures, this benefit may be essential.
The general premise of a butterfly valve is that a large disc is situated inside a pipeline. As the disc is moved into various positions, it either allows a substance to pass further into the pipeline, or it prevents it from entering. When a lug butterfly valve is in the closed position, it creates a reliable seal that prevents gases or liquids from traveling beyond a certain point. The perpendicular placement of the round disc in relation to the pipeline creates a closed valve position. If the round disc of a lug butterfly valve is moved so that it is parallel to the pipeline, the valve has been opened, and gases as well as liquids can then pass by the disc by using the spaces on either side.
A lug butterfly valve is not actually removed from the system when it is in the open position, it is just moved so that it does not completely block the flow of substances. Regardless of the placement of the valve, when it is open and allowing flow to pass by, there will still be a drop in pressure. The pressure drop may not be a desirable side effect for businesses looking to install a lug butterfly valve, but the lighter cost and weight of the butterfly valve makes it a favorable choice. The lighter weight allows for less pressure to be exerted for the butterfly valve to still be moved and its position changed.
A lug butterfly valve is classified as a quarter-turn valve. The basic design of these valves is that a disc is connected to a shaft, and the shaft is moved to determine the position of the valve. A lug butterfly valve, like other members of the quarter-turn valve family, can be composed of a variety of metal and plastic materials. Each company needs to consider the material that would meet their needs more effectively, without creating the need for extra cleaning and maintenance.
