Armstrong AB-600 bimetallic steam trap operates by the effect of temperature rise on the thermostatic bimetallic element. The force generated by the thermal deformation of the bimetallic element in the valve increases with the increase of temperature, which can compensate for the increasing pressure on the valve, so it can automatically adjust with the change of working conditions.

Installation

Possible connections for the AB-600 include screwed, socketweld, or flanged.

Maintenance

WARNING

Equipment under pressure - Operating temperature > 100°C - Make sure trap is cold before handling!
