STEAM TRAPSTEAM TRAPSTEAM TRAPSTEAM TRAP■■■■

Steam traps are automatic valves that release condensed steam (condensate) from a steam space while

preventing the loss of live steam. They also remove air and non-condensable from the steam space.

Steam traps are design to maintain steam energy efficiency by performing specific tasks such as heating

a building or maintaining heat for process.

.

The mechanism that automatically adjusts the pressure in pressure reducing valves uses the balance

between the steam pressure and the adjustment spring.

The steam flowing through the pilot valve is controlled by the balance between the adjustment spring

and the secondary pressure. This steam causes the piston to fall and rise, which controls the amount of

opening of the main valve.
