Velan Design - Velan Float & Bimetallic
FAST WARM UP
Clearing air and moisture from a cold system rapidly reduces warm-up time
and increases production. Other float traps must have a separate air venting
facility while the Velan MFT utilizes the large main orifice for the fastest
warm-up time of any comparable sized float trap.
POSITIVE TRAPPING
When condensate is discharged, the float mechanism rests on the trap body.
The bimetal element alone, closes the valve with thermal power developed by
incoming steam. The bimetal element is a function of the saturated steam curve,
therefore operates efficiently at any pressure within it’s range.
CONDENSATE DISCHARGE
If condensate builds up in the trap body, the float becomes buoyant, and
opens the valve to unrestricted flow. Condensate even at steam temperature
is discharged at the same rate as it reaches the trap. No air binding or water
logging irrespective of adverse conditions. The trap drains by gravity and will
not freeze.
CHECK VALVE ACTION
When pressure is off, equipment discharging to a common return, or where
condensate is returned to overhead lines, a check valve is required to prevent
reverse flow through the trap. The free-floating MFT mechanism shuts immediately
the reverse flow and no additional device is required.
