Detailed Photos
The float valve joint is mainly composed of float, valve disc, valve stem, seat and other components. The float is usually connected with the valve stem. When the liquid level rises, the float rises and drives the valve disc to open through the valve stem. Conversely, when the liquid level drops, the float drops and the disc closes.
The float valve joint can automatically open or close the valve according to the rise and fall of the liquid level, without manual operation, improving work efficiency and automation. The structure of the float valve joint is simple, and the internal moving parts are few, so it has high reliability and stability, and is suitable for all kinds of harsh working conditions. Float valve connectors can be used to control the level of various liquids, such as water tanks, pools, etc., and can also be used to control wellhead pressure in downhole operations.
