BARNES & JONES 4175 Cage Unit 1" Type-B Bronze Bellows

The BARNES & JONES 4175 Cage Unit operates as an essential part of steam heating systems to serve HVAC equipment including steam radiators and heat exchangers. The 1" Cage Unit uses bronze bellows to operate as a thermostatic steam trap. This system effectively removes condensate and air from steam systems and stops the loss of live steam. The bronze bellows operate through temperature changes which cause it to open and discharge condensate during cooling and close to maintain steam during heating. The installation of this unit leads to better heating performance and decreased energy usage and reduced water hammer effects.
