ACT Check Valve Unions are designed to seal off well pressure in the event of the wireline parting from the tool string. The steel ball is forced against the metal sealing area by the well pressure from below. The check valve unions are manufactured as one piece body and are assembled below the stuffing box or grease injection control head. The internal check valve assembly can also be fitted as an integral part of the stuffing box or grease injection control head. This helps to reduce the height of lubricator assembly.
