Free Float Steam Traps are used in
oil and gas, pipeline, petrochemical, paper, utility, food, industries. Ideal for steam
main, steam heating system and condensate recovery system.
Free Float Steam Traps prevent the steam put effectively discharge sweat quickly.
Especially suit for technical process that requires fast heating speed, controls heating
temperature strictly, no pile-up sweat in heater assembly. |
| PRINCIPALE OF OPERATION: |
|
1. Start up, the
valve air vent opens wide to continuously discharge initial air.
2. As condensate comes into the traps, the float rises to allow condensate to be
discharged from valve seat.
3. Hot condensate( up to steam temperature) comes into the trap heated Bimetal_element to
close valve air vent, before steam reaches the trap but condensate coming into the trap
continues to be discharge through valves seat
4. When condensate flow to the trap stops, the float closes valve port( valve seat)which
is, in addition always sealed below the water level., prevent any steam leakage. |

| FEATURE PRODUCT: |
|
 |
No concentrated wearing, long duration; |
|
Good property of sealing, low steam leakage, notable energy-saving effect;
|
|
Set with adevice of air exhaust, able to quickly start and continuously
drain condensated water; |
|
High rate of backing presssure, low degree of undercooling, helpful to
utilize the condensated waer by recovering; |
|
No noise, easy to repair, good interchangeability. |
