Application Example : heat exchanger, press, sterilizer, end of line, etc.
• Discharge capacity required, in pounds per hour (lbs/hr).
• Physical constraints, reduced space, vertical or horizontal installation.

It is always recommended that the steam quality be taken into account when selecting your trap. Are there solid deposits (scale, metals ...) in your line that could harm your steam trap? The thermostatic steam traps are fairly sensitive to scale and other deposits. However, they offer better efficiency, more precision and are completely hermetic.

When installing a steam trap, it is recommended that a Y strainer be installed before the trap, and a check valve after.

Here are the four general types of steam traps:


Float and Thermostatic, Free Float

Inverted Bucket Trap
