Steam Traps

(OP)
What is technically a modulating steam trap? Bucket?
And what is considered a constant flow trap? Float Traps or modified Float traps or neither?

RE: Steam Traps

Modulating and Constant flow should be the same thing when considering steam traps. Certain types of traps will work as on/off (disc or often called thermodynamic traps), or modulating (float & thermostatic). Bucket type traps can work both on/off and modulating depending on the flow coming into them. Thermostatic type of traps are usually modulating but some are designed as on/off.

All traps should shut off when there is no condensate.

All traps will stay open when there is condensate.
