Barnes & Jones Radiator Steam Trap Documentation

Barnes & Jones Radiator Trap Description

Every Barnes and Jones radiator steam trap is factory calibrated the Barnes & Jones test facility. Steam Trap calibration ensures that each of trap shuts to steam and opens to condensate with uniform sensitivity. No longer will you worry about the tolerances of individual parts like the screw-in seat, lock washers, element and cover of other traps. Barnes & Jones Radiator Traps are special because they feature the famous one piece, fully removable, thermostatic element... the cage unit. Also, since testing of the cage unit can be performed out of the original steam trap body, it eliminates the need to take the trap offline for testing and repair. This alone will greatly simplify your preventative maintenance program.

  • Corrosion resistant seat and plugs with the option of stainless steel
