Abstract
Disclosed is a device configured for a valve. The valve has a valve structure that is configured to include an outlet body configured to define an outlet. The outlet body is also configured to attach to a melt processing screw of a molding machine. The valve structure is also configured to include an outlet cover configured to selectively close and open the outlet. The device includes a brake configured to decelerate the outlet cover responsive to deceleration of the outlet body, and the decelerating outlet cover maintains the outlet substantially closed.
