Overview
In today's world of automation, compressed air is used in many industries including high-precision machinery and instrumentation. After air is compressed it is cooled by an after-cooler or in a receiver tank, where condensate is formed from water droplets in the air.
This condensate also occurs in compressed air distribution piping, leading to rust and fluctuation in high-precision machinery, as well as causing a reduction in product quality.
TLV air traps protect your equipment and products by discharging condensate automatically.
Features
Long Service Life
The hinge-less free float has only one moving part, allowing for simple operation. With infinite sealing surfaces, the free float does not suffer from concentrated wear, maintaining initial performance quality over a long time period.
Continuous Condensate Discharge
The float adjusts quickly to changes in condensate flow adjusting the valve seat opening, ensuring continuous rapid discharge without condensate backup.
Rubber Valve Seat for Tight Sealing
The standardized rubber valve seat allows for tight sealing with the precision ground float.
Valve Seat Cleaning Mechanism
Equipped with an external plunger unit, blockage caused by oils and/or scale can be easily eliminated.
The valve seat cleaning mechanism enables removal of scale and other debris from the orifice. Debris is forcibly removed when the needle pierces through the blocked orifice, simultaneously pushing the float off its seat. This mechanism may help save time by removing light debris that causes blockage without having to completely disassemble and reassemble the air trap for maintenance.
Applications
Applications by Series
JA series
- Discharge of condensate in air lines (end of piping after receiver tanks, after coolers, etc.)
- Small compressed air lines (JA3D, JA3)
- Medium compressed air lines (JA5)
- Larger compressed air lines (JA7, JA8)
G8
- Designed to discharge high viscosity condensate, such as when oil is mixed in with the condensate
Application Drawings
Air traps automatically discharge condensate that has entered the trap body. However, air can remain trapped within the body and completely block discharge (a problem known as "air binding"). A balancing line can be installed to remediate this problem.

Operation Animation
JA series
As condensate enters the trap, the float rises off the valve seat. The amount of condensate controls the size of the opening. With the valve open, condensate is continuously discharged.
At times when the condensate load increases significantly, the float is completely lifted off the valve seat, fully opening the valve and thus increasing the condensate discharge capacity.
If no condensate enters the trap, the float lowers onto the valve seat, closing the valve opening.
