Abstract: An assembly for removing liquid from a pressurized gaseous system, such as condensate from a steam line, contains a rotatable stopper member with a restriction orifice which provides for removal of condensate with only a minor, controlled loss of steam. The orifice can be rotated 180.degree. to the pressure flow, thus allowing the pressure to blow out any trash that becomes lodged on or in the orifice. The stopper member can additionally be rotated so that a larger blow-down port is in the line of flow, thus permitting the removal of trash and excess liquid that may accumulate in the line.
