DDifferential pressure bar (x 100 = kPa)
Under start-up conditions when the condensate is cold the internal thermostatic air vent will be open and provides additional capacity to
the main valve. The Table below gives the minimum additional cold water capacities from the air vent.

How to order
Example: 1 off Spirax Sarco DN40 FT54H-4.5 ball
float steam trap with carbon steel body and cover. Flanged connections to EN 1092 PN40.
Trap to be fitted with the optional balance and drain connections.
Note: If the product has the optional steam lock release fitted the nomenclature would be FT54-4.5-C.
