Abstract
An apparatus includes a stem connector configured to connect a movable piston with a valve stem, in which the movable piston is slidably receivable in a cylinder, and in which the cylinder is mountable to a distribution manifold of a molding system. The stem connector maintains connection between the movable piston and the valve stem while the valve stem is moved to selectively open or close a mold gate of a mold assembly installed in the molding system. The stem connector urges the movable piston to tilt at a tilt angle while the movable piston is moved along an interior of the cylinder, and in which the tilt angle is formed between a central piston axis extending through the movable piston and a central stem axis extends through the valve stem.
