STEAM TRAPS MECHANIC STEAM TRAPS THERMODYNAMIC STEAM TRAPS THERMOSTATIC STEAM TRAPS
THERMOSTATIC STEAM TRAPS Typical characteristics of thermostatic steam traps is to operate according to the difference in temperature of steam and condensate. As the condensate cool, the liquid condenses lowers the internal pressure of the membrane. The resultant pressure differential will favour the external pressure acting on the membrane to retract and open the orifice, permitting the condensate discharge. TKK-2Y TKK-3 Increasing the discharge capacity: Condensate discharge capacity could be increased by increasing the number of the capsules used in the body design. The discharge capacity is dependent on the type and number of the capsules as well as the size of the steam trap.
THERMOSTATIC STEAM TRAPS Operation Principals; At the start up position, the trap is completely open and removes the air and dis-charges the condensate. When the temperature reaches the saturated steam level related to the pressure, vaporization of the liquid inside the thermostatic capsule membrane creates a pressure differential causing the close the orifice.

THERMOSTATIC STEAM TRAPS
BI-METALLIC STEAM TRAPS Highly resistant against corrosive condensate and water hammer. Long reaction time for load and temperature changes may cause trouble at the equipment. Operation Principals; TK-1 As the fluid is cold, bimetal elements are compressed and the valve is open. Air, non-condensable gasses and condensate are discharged during this stage. When the hot condensate enters the system, bi metallic plates expand with different amounts and pull the valve toward to the seat and stop discharging.

THERMODYNAMIC STEAM TRAPS Features; - Small and light, easy installation - Only movable element is the disc, So the maintenance is easy and cheap. - High efficiency due to fast reaction for discharge. TDK -45 - Wide operation range; - 0,25 bar 42 bar - Not affected from water hammering thanks to firm body and construction - Both horizonlal and vertical installation is possible
THERMODYNAMIC STEAM TRAPS Operation Principals: - If cold condensate flows into the steam trap on start-up, the valve disc is forced upwards and the condensate is discharged from the outlet holes - Steam trap senses the dynamic difference between flash steam and condensate and discharges 2-3 C below the steam. - Thermodynamic steam trap does not have steam leakage, flash steam may be considered as leakage.

INVERTED BUCKET TYPE STEAM TRAPS Advantages; 1- Strong structure 2- Resistant to water hammer 3- Resistant to corrosion 4- Resistant against pollution Disadvantages; 1- Slow discharge 2- Steam leakage possibility at low loads 3- Not suitable for super-heated steam lines BT-16
INVERTED BUCKET TYPE STEAM TRAPS Operation Principals; At first, the bucket is at the bottom and discharge nozzle is fully open. Air and gases are discharged Steam trap senses the density difference between steam and condensate and discharges.
FLOAT TYPE STEAM TRAPS Features; - The most ideal steam trap for automated systems. - With the adaptability to the systems with very low pressure difference and high discharge capacity, can meet the expectations. - Not affected from sudden and high pressure loads. SK-51 - Stainless steel internals prevent corrosion - Steam traps with thermostatic air vents are able adjust themselves according to unsteady pressure loads
FLOAT TYPE STEAM TRAPS Operation Principals: While the system is cool, the coming air is discharged from the discharge unit. Steam trap senses the density difference between steam and condensate and discharges. As it is designed that always some water stays on the valve system, water sealing is provided. SFK-40 SK-51

STEAM INSTALLATIONS In a system, an appropriate diameter is required to transfer a certain amount of steam at a certain pressure. If a lower diameter were selected, there would be high pressure drops, high steam velocity, noise and abrasion. If a higher diameter were selected, there would be both increased heat loss and costs.
