SS304 250MM Ball Size BSP Male Threaded End 2Inch DN50 Float Ball Valve for the Tank

Float ball valve is a valve composed of curved arms and floating balls, which can be used to automatically control the liquid level of a water tower or pool.
Float ball valve is a ball without a supporting shaft, which is held in a "floating" state by two valve seats. It is mainly used for cutting, distributing, and changing the direction of medium flow in pipelines. Floating ball valves mainly have structural features such as valve seat sealing design, reliable reverse sealing valve stem, fire and static electricity prevention function, automatic pressure relief and locking device.

The float always needs to float on the water, and when the water rises, the float also rises. When the float rises, it drives the connecting rod to also rise. The connecting rod is connected to the valve at the other end, and when it rises to a certain position, the connecting rod supports a rubber piston pad to seal off the water source. When the water level drops, the float also drops, and the connecting rod drives the piston pad to open.

Float valves regulate the liquid supply by controlling the liquid level. A full liquid evaporator requires the liquid level to maintain a certain height, and it is generally suitable to use a floating ball expansion valve. The working principle of a float valve is to control the opening or closing of a valve by lowering and raising the float ball in the float chamber under the action of the liquid level. The floating ball chamber is placed on one side of the full liquid evaporator, and the upper and lower parts are connected to the evaporator through a balance tube, so the liquid level height of the two is the same. When the liquid level in the evaporator drops, the liquid level in the floating ball chamber also drops, so the floating ball drops and relies on the lever to increase the valve opening and increase the liquid supply. vice versa.
