Pressure relief valve apparatus, system and method

A valve apparatus, comprising:

• a hollow body having an inlet and an outlet, the hollow body including at least one aperture extending through a surface of the hollow body;
• an actuator assembly coupled to the hollow body;
• a sleeve slideably positioned about the hollow body, and moveably coupled to the actuator assembly;
• a first pivot plate rotatably coupled to the hollow body at a first pivot point, the pivot plate including a slot that is sized to receive a pivot pin that extends from the sleeve;
• a second pivot plate rotatably coupled to the hollow body at a second pivot point located opposite the first pivot point;
• and
• a first strut coupled to both the first and second pivot plates;
• where the actuator assembly includes a rod that is coupled to the first strut, so that the actuator assembly can move the sleeve from a first position that covers the at least one aperture to a second position that un-covers at least a portion of the aperture;
• where the actuator assembly further comprises:
• a housing having a diaphragm located within the housing;
• a piston located adjacent to the diaphragm;
• an actuator shaft having a first end coupled to the piston and a second end extending from the housing and coupled to the first strut;
• where the actuator shaft includes a pivot link at a distal end of the actuator shaft, with the pivot link coupled to the first strut and structured to rotate relative to the actuator shaft.
