Claim:
1. An apparatus for actuating a valve, the apparatus comprising: an actuator body with a proximal end and a distal end, the proximal end having a connector selectively coupled to a valve assembly; a piston assembly located within the proximal end of the actuator body that comprises a piston disposed in a piston cylinder, the piston cylinder being static relative to the actuator body; a telescoping port assembly with a central axis, the telescoping port assembly extending from the distal end of the actuator body to the piston assembly and having a first end fixed to the distal end of the actuator body and a second end movable with the piston within the piston cavity, the telescoping port assembly having an inner telescoping member and an outer telescoping member with an inner cavity that reciprocatingly receives an end of the inner telescoping member; and a bore that extends axially through the telescoping port assembly and that communicates pressure from a pressure source to the piston cylinder, so that when a pressure media is supplied from the pressure source to the bore, the piston is axially moved to actuate the valve assembly, and the outer telescoping member telescopes outward from the inner telescoping member.
