Abstract: A pivoting mechanism for use in a high temperature steam distribution system includes an input member operative to move between a low level position and a high level position. A compression spring having a first end and a second end is also provided. The first end of the compression spring is connected to the input member. A pivot member is operatively connected to the second end of the compression spring. The pivot member rotates in a snap over fashion to a first position when the input member reaches the upper position. When the input member reaches the lower position, the pivot member rotates in a snap over fashion to a second position.
