1.
After the installation, air exists in the product, and the float [9] is lowered by its own weight. In this
condition, since the valve disc [5] is kept open by the lever [7], air is discharged outside by the internal
pressure of the system.
2.
When air is discharged, hot or cold water flows into the product to make the float [9] come up on
buoyancy and the force that keeps the valve disc [5] open through the lever [7] is lost. Then the valve
disc [5] is closed by the spring [6] and pressure to the valve disc [5].
3.
When air bubbles are generated in the system and collected into the product, the inside water level
drops, and the float loses buoyancy and opens the valve disc [5] to discharge air.
4.
Then the operation goes back to the above process [2]. Repeating the processes [2] and [3], air in
the system can be removed.
The above drawing shows the structure of the TA-16. The TA-16L has L-shaped hose joint screwed in the
seat [3]. The TA-16CVA and TA-16CVS have check valve joints (the CV-16A and CV-16S respectively)
screwed in each seat [3].
6.1 Precaution before use
1. Make sure to attach joint and hose to outlet of the product, and lead them to drain ditch.
* Failure to follow this notice may contaminate the surroundings, result in burns for high-temperature
fluid or cause bodily injury or damage to the property when valve leakage happens.
2. Install the product vertically to a place where air is easy to accumulate.
* Failure to follow this notice may prevent the product from functioning properly.
3. Before installing the product, remove foreign substances and scale from the piping.
* Failure to follow this notice may prevent the product from functioning properly.
1. Install stop valve (cock or gate valve) to inlet of the product for maintenance and inspection.
2. Plumb the exhaust outlet in a way that prevents backflow.
