Automatic Water Level Control Valve Dn20

Automatic Water Level Control Valve Dn20                                                                                    

Specification                                                                                                  

The fully automatic water level control valve is a patented substitute of the original built-in ball float valve.
This fully automatic water level control valve is a patented product Instead of traditional float valve, it has been widely used in automatic water feed system of various water boxes water tanks and water towers, commercial water heating boilers, solar energy systems, air cooling machines, humidifiers, cooling towers of industrial and mining enterprise and civil construction etc. Work principle: When water level of water tank or water box falls down, the float in the cavity sinks and triggers the lever to pen the pilot hole of control valve, the sealing surface of control valve will open under the action of pressure of water the channel, and the water will flow out from the control valve; When water level rises to control Ilne, the float will rise to trigger the lever to close the pilot hole, the cavity begins to be filled with water, so as to close the sealing surface of control valve, and the control valve will stop supplying water at once. Product feature: Small volume, high water discharge.

Technical Data

1. Applicable medium: Clean water;
2. Work pressure range: 0.02MPa~1.0MPa
3. Applicable medium temperature: 60 degree
4. Applicable medium temperature for high
Temperature ball float: 60~120 degree

Working principle 

When the water level in the tank descends, the floater In the valve chamber sinks, which drives the lever to open the pilot hole of the control valve, the sealing surface of the control valve is opened by the water pressure in the pipe, and thus the water flows out through the control valve; When the water level rises to the control Ilne, the floater raises, which drives the lever to close the Allot hole, the water begins to fill the chamber to close the sealing surface of the control valve, and thus the control valve stops water supply immediately.
