The “Clean Trip” Dump Valve is a multi-activating valve used to establish circulation from the drill string to the annulus. The valve is designed as a normally open valve to allow the drill string to fill while going in the hole. Once on bottom, pump flow actuates the valve and shuts off flow to the annulus and diverts all flow to the mud motor.  Shutting down the pumps allows the valve to open reestablishing communication to the annulus allowing the drill string to pull dry.
