Product Working Principle: (Refer to Figure 3)
Figure 3 shows a simple float trap operational representation. A float trap works on the Buoyancy
Principle. Condensate enters the trap body and raises the float
(1)
. The position of the float
(1)
depends
upon the level/load of condensate (flowrate). The float trap continues to discharge condensate
continuously and doesn't allow back up of condensate as long as the load is within the discharge
capacity. When the condensate load drops, the float
(1)
lowers in position and closes the outlet valve
(3)
with the ball
(6)
resting on the orifice
(7)
.
SLR
(4)
is a needle valve which releases steam that can steam lock the trap during start-up or in
operation if the steam reaches the trap before the condensate.
On the start up the air present in the pipeline/process equipment is released through the thermostatic
vent

.

*The trap in the figure 3 shows a TV+SLR assembly. SOFT31(DN15-25) also comes with only TV or SLR assembly.
