A valve pin actuating device for a hot runner apparatus includes a yoke plate coupled to actuators. The actuators are generally disposed at the ends of the yoke plate and are configured to move the yoke plate in a direction parallel to a longitudinal axis of the valve pins. A deflection distributor apparatus is coupled to the yoke plate. The deflection distributor apparatus is connected to a first force distributor plate, to which the valve pins are connected. The deflection distributor apparatus includes a second force distributor plate and a third force distributor plate. Rods are disposed between the yoke plate and the third force distributor plate, between the third force distributor plate and the second force distributor plate, and between the second force distributor plate and the first force distributor plate holding the valve pins.
