Abstract
A sub-surface safety valve having a positional flapper, a valve seat, and a remotely actionable opening prong. The opening prong comprising at least one of a debris wiper, filter, and at least one flow hole. The wiper, filter, and at least one flow hole function according to either position or movement of the flapper and opening prong and prevent debris buildup around the valve seat. The wiper is an extendible material in communication with the valve seat and a surface of the opening prong and it extends radially in response to closing the valve. The extension of the wiper in response to closing the flapper cause the wiper to scrape the surface of the valve seat. The filter can comprise a screen integrated with or attached to the opening prong. The flow holes can be in the form of angled flow holes or elongated slots.
