Frequently Asked Questions
Will a Velan bimetallic steam trap back up condensate and possibly break
the steam line due to waterhammer?
No. The Velan design will not sub-cool large amounts of condensate. The
Velan multi-segmented bimetallic
design follows the steam curve and will hold
a maximum of 12-18 inches of water in a ¾” pipe in front of
the steam trap. The Velan design will constantly modulate condensate
out and drain the line better than intermittent blast-on / blast-off designs in
the marketplace.
Excessive waterhammer due to condensate backup can happen
with any steam trap design that is not sized properly.
