Model 41-01 float valve is hydraulic pressure controlled and can maintain the water level at a stable level in the tank by using a pilot to control the diaphragm control valve. The float pilot is installed at the high-water level in the tank and connected with the main valve. When the water level is changed, Pilot will open or close the valve accordingly and maintain the water level in the range.
If a check feature is added, and a pressure reversal occurs, the downstream pressure is admitted in the main valve cover chamber closing the valve to prevent return flow.

Notice：

※When installing the valve, strongly request to leave enough space for maintenance. It is necessary to install the filter at the front section of the valve to avoid foreign materials to block the valve and affect the operation of the valve.

 

※King-Tech reserves the right to make any revisions on the valve model and size without prior notification.

 

※When making any design drawing, installation drawing or construction drawing, please do get our approved CAD with our signature, or we will not be responsible for any mistake.

Typical Application

 

 

 

 

The installation of valve and float ball switch is as illustrated.

 

The float ball switch is installed at the outlet of the connecting pipe, and fixed at the pre-set water level. The valve outlet must be far away from the float ball switch at least 5 meters away.

 

Suggest to install a smoothing & calming valve at the outlet to avoid the wave of outlet water which will cause the valve tap opened and closed frequently and make vibration noise to shorten the valve life.
