A valve that automatically controls the level of a vessel. It is installed in the liquid inlet or outlet of the container, the use of float (usually empty floating ball) in the container float or drop drive valve disc action, by regulating the flow in and out of the container to maintain a certain level of the container. The valve in the figure is a floating ball regulator that controls the inlet flow of fluid. When the liquid level is below the specified value, the float drops to open the disc, and the liquid flows into the container, and the liquid level rises accordingly. When the liquid level rises to the specified level, the float floats to close the disc and the liquid stops flowing in. These valves are used for level control in low pressure vessels.

Butterfly Valve (English: butterfly valve) is the closing piece (disc or disc) for the disc, rotating around the valve shaft to achieve a valve on and off, mainly in the pipeline cut off and throttling purposes. Butterfly valve opening and closing pieces is a disc-shaped disc, the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation. The butterfly valve fully open to the whole is usually less than 90 °, the butterfly valve and the butterfly itself does not have self-locking ability, in order to disc positioning, to install a worm reducer on the stem. The use of worm reducer, not only can make the disc self-locking ability to stop the butterfly plate in any position, but also to improve valve performance. Industrial butterfly valve features high temperature, high pressure range, the valve nominal diameter, the valve body made of carbon steel, the valve ring using a metal ring instead of rubber ring. Large high temperature butterfly valve welded steel manufacturing, mainly for high temperature medium smoke duct and gas pipelines. Search Keyword: More Valve Technical Articles
