Abstract: A thermostatic steam trap is described wherein a thermostatic actuating means including a valve is mounted for axial movement of the valve into and away from sealing contact with a valve seat positioned axially of the hollow cylindrical body of the steam trap by a circular baffle which loosely engages both the actuating means and portions of the body of the steam trap. The baffle is oriented transversely of the hollow cylindrical body at the inlet end of the steam trap and has nonarcuate segments formed upon its periphery, thereby causing diversion of the steam flow away from direct impingement upon the thermostatic actuating means, while ensuring good heat transfer to the thermostatic actuating means. This construction provides for a self-centering steam trap valve.

Abstract: A gasketed pipe union has an annular connection stub on one section of pipe forced against a connection ring on a second section and held by a lock nut. A gasket and retaining and centering device, pressed between the stub and ring, insure a seal between the two sections.
