Method of Operation |
|||||
ZN170 |
Float valves work in conjunction with floats to control the level of |
||||||
|
|
liquids in containers. The float is at the level of the liquid in the |
|||||
|
|
container and acts directly on the lever arm of the float valve. A |
|||||
|
|
variation in liquid level immediately causes a change in the flow |
|||||
|
|
rate through the float valve. |
