What is Manual Override? What is the Visual Indicator for the motorized ball valves?
* Manual override is only permitted to use occasionally when power is off, If one specifies Manual Override that it automatically has the visual indicator.
* if you have to use the manual override,please operate very carefully,lift the button very gently and turn it left or right until the valve is in place,do not forget to press down the button after operation finished,


If you think manual override is very important in your application,please tell us you need it,we will equip with a Manual Override button on the actuator,see below picture,
If you want to see the valve position of valve open or close,please select the Indicator Window function(visual indicator), we will equip with a visual display window on  the actuator.see below picture,

* If you do not mention manual override and visual indicator,we will provide valves without manual override and with visual indicator,(this is our default configuration),

 

 


Manual override and visual indicator are optional functions,there will have additional cost,

If you need manual override,the price will be increased approx $3.0-6.0 usd/pc,
If you need visual indicator,the price will be increased approx $0.8-2.5 usd/pc,

 

Manual override is just optional function, there is an additional cost for this function,so if manual override is not very important we do not recommend it,
Visual indicator is useful and there is nearly no additional cost,we recommend it,


*For Model TOFINE-THA20T,So far Manual override is only available for 5V,12V or 24V,not available for 110V~240V.

How to operate Manual override? Manual override is only permitted to use when power off, "O"-open, "S"-close.Lift the button and turn it left or right gently,Don't forget to press down the button after power on.
Visual indicator can indicator the valve open or close position.When line parallel with pipe,the valve open,when vertical,valve close.
 

1. It is only permitted to use when power is off.
2. Lift the hand-wheel gently and turn it left or right until the valve is in place.
3. When the red line on the indicator points to "S" the valves is closed;when "O" the valve is open. 
4. 
Press down hand-wheel when manual override operation is finished so that the valve can work properly when power is supplied.(Don't forget to let manual override button back to its original position when manual override operation is finished)
