ABSTRACT:
A T-shaped pipe whose base extends through a sidewall of a steam trap housing terminates internally of the housing in open ended upper and lower vertical arms. The lower arm is closed off by an axially movable valve disc mounted to a valve actuator rod extending axially through the arms and coupled at its upper end to a pressure balancing plate sealably connected at its periphery by a non-ferrous metal bellows to the upper end of the T-pipe arm. A float ball fixed to a float arm is pivotably coupled at the opposite end of the arm to the valve actuator rod and to the T-pipe with the pressure on balancing plate balancing the pressures acting on the movable valve disc.
