Abstract: A device for draining condensate from a steam system while substantially eliminating the passage of steam. The device has flanged inlet and outlet ends and includes a unitary Y-shaped body defining a fluid flow conduit, a filter device disposed within the Y-shaped body, and flanged inlet and outlet body ends configured for corresponding bolted connection with the flanged inlet and outlet ends of the steam system. The device also has an insert housing removably connected within the Y-shaped body and abutting the flanged outlet end of the steam system, and a nozzle structure removably positioned within the insert housing and having a constricted passageway in fluid communication with the fluid flow conduit. The insert housing can only be removed from the Y-shaped body by first disconnecting the Y-shaped body from the steam system, providing added safety for steam system operators.
