Abstract
A wellbore servicing system and method are disclosed. The wellbore servicing system includes a casing string and a pressure testing valve. The pressure testing valve includes a housing, a sliding sleeve, and a deactivatable locking assembly. The housing includes ports and an axial flowbore. The sliding sleeve is positioned within the housing and is transitional between first, second, and third positions. When the sliding sleeve is in the first and second positions, the sliding sleeve blocks fluid communication via the ports. When the sliding sleeve is in the third position, it does not block such fluid communication. Application of a fluid pressure transitions the sliding sleeve from the first to the second position, and a reduction in fluid pressure transitions the sliding sleeve from the second to the third position. When activated, the locking assembly inhibits movement of the sliding sleeve toward the third position.
