The purpose of a steam trap is to prevent steam from passing its point of use, and to allow condensate to be expelled as soon as it forms. Barnes & Jones thermostatic steam traps do this very well. So well, in fact, that the company says it performs this function better than any other steam trap on the market today — because it’s the only factory-calibrated thermostatic steam trap available.
How it works
Thermostatic steam traps are balanced pressure devices that use vapour pressure, within a diaphragm or bellows, to open and close a valve in a modulating manner, dependent upon the temperature surrounding it. The trap is normally open to expel air and condensate. As saturated steam surrounds the unit, the volatile fill inside the element flashes into a vapour, creating an internal pressure. This equalization of pressures allows the element to expand to its natural length or “closed position”, preventing steam from passing its point of use. The presence of condensate will cool the element and condense the vapour within, reinstating the vacuum, causing the element to retract to its open position and allowing the condensate to drain from the trap.
Edison/Barnes & Jones thermostatic steam traps
Edison/Barnes & Jones thermostatic steam traps, available from Keystone Steam Supplies, are equipped with one-piece, self-contained “cage units” that are 100 per cent factory calibrated and tested under live steam and condensate to ensure uniform operation in the field. The one-piece, self-contained design allows for the ease of inline repair. There are no piping connections that need to be broken, or multiple internal components to be removed. The body of the trap acts merely as a housing for the “cage unit”, which performs the actual steam trap functions.
Ideal for all outdoor applications and all process applications (especially batch processes) up to 250-pound pressures, thermostatic traps have a large water and air handling capacity.
