Will new TD trap passes steam?
(OP)
Hi,
I am wondering will a new TD steam trap passes any steam during operation? I heard that a perfect condition TD trap will still passes some steam.
Thanks.

1/ They are routinely GROSSLY oversized.
2/ They are routinely installed on applications where they should not be.

It will of course allow some through before it closes.

At low differential pressures the trap will fail open and pass live steam. I usually do not recommend these traps for systems under 50 psig.

A space above the disc keeps it seated until the pressure drops.
Best speaking to spirax sarco or one of the other big ST manufacturers to ascertain which trap is suited to your application.
Incidently, what is that?

1. The ambience is very cold (insulated cap TD traps are developed to tackle this issue)
2. If there is any debris between the disc and the seat (fine welding flux etc.)
