Abstract
A float actuated valve mechanism for automatically removing a predetermined amount of accumulated liquid condensate from a sump area of a gas pressurized drain trap or the like so as to regulate the level of liquid in such a sump area. A four-bar linkage between a float and a valve plug provides a non-linearly varying mechanical advantage throughout the movement of the float. In a closed position the valve plug mates with a rigid seating surface and an elastomeric seating surface to provide a wear-resistant seal.
