Double Orifice Float Trap Module



Steam has two different kind of heat : The Latent heat and the Sensible heat. Whereas condensate has only sensible heat. This condensate must be removed as soon as it is formed, because it hampers the efficient heat transfer and leads to water hammer phenomenon due to hot water (having more Specific Gravity) that moves with high velocity of steam (8 to 10 times higher than water), carrying enough
momentum to rupture pipes, damaging the plant pipelines and piping equipment’s. Hence, need to remove condensate from steam main and trap steam. This is done by steam trap.

UKL Ball Float Trap discharge condensate near to steam saturation temperature, which works on the principle of Buoyancy, [density difference of Water and Steam].The rising condensate level elevates the Float open the valve and discharges the condensate. When the level of condensate drops, the float falls and the valve close the trap.

It is commonly used in most of the process heating applications, where steam is used for indirect heating application. Normally these traps are of mechanical design. A double orifice float trap is a mechanical type having continuous discharge. A double orifice pin is connected to a single float by unique interlink lever bracket arrangement. This trap efficiently handles different load condition like initial load, running load and peak load. DOFT M is having in-built Inlet isolation valve, outlet isolation valve, By-pass valve and integral strainer. This trap is provided with SLR valve seat arrangement or Thermostatic vent. The TV will ensure effective removal of air and other un-dissolved gases will be automatically vented out when present in condensate.
