Abstract
A fluid regulating device comprises an actuator with upper and lower housing components. The upper and lower housing components are secured together at mating flanges via a plurality of fasteners. The upper housing component is formed with a vent to contain a relief valve, which exhausts fluid to the atmosphere under overpressure conditions. The upper housing component is constructed such that it does not require a pedestal or fins extending between the vent and the flange, which advantageously provides a completely unobstructed, continuous, ring-shaped flange for receiving and manipulating the fasteners during assembly and/or maintenance of the regulating device.
