Abstract
An apparatus for actuating a valve includes an actuator body with a proximal end having a connector for coupling to a valve assembly, and a distal end. A piston assembly having a piston disposed in a piston cylinder is located within the proximal end of the actuator body. A telescoping port assembly extends from the distal end to the piston assembly, the telescoping port assembly having an inner telescoping member and an outer telescoping member. The outer telescoping member has an inner cavity that reciprocatingly receives an end of the inner telescoping member. A bore extends axially through the telescoping port assembly and 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 actuates the valve assembly, and the outer telescoping member telescopes outward from the inner telescoping member.
