Thermostatic Steam Trap Operation


UKL Thermostatic trap has a unique Simple design, Minimum number of components and where the Bellow is enclosed and protected thus ensuring long life for the Bellows. These Traps used largely on tracing line or Tank farms where steam is supplied to maintain Temp/Viscosity of the oil.

Thermostatic Operation

This trap works on the difference in Enthalpy of Steam and Condensate. Condensate temperature is used to open the trap by contracting the capsule, discharging condensate in low temperature. A capsule attached to a Bellow filled with precise amount of a Hydrocarbon, Expands and contracts in response to the rising/lowering of Enthalpy. 

Thereby shutting and opening the valve. Condensate has lower Enthalpy, causing the bellow to contract and the seat to retract which opens the valve and allow discharge of condensate and expands as soon as it comes in contact of Hot steam, causing seat to close the valve.
