Abstract

An example valve described herein includes a bonnet having a bonnet cavity defining a bonnet inner surface, a bonnet outer surface, and a first pressure sensing passageway extending between the bonnet outer surface and the bonnet cavity. A base is coaxially coupled to the bonnet and has a base outer surface, a base cavity that defines a base inner surface, a fluid inlet passageway extending between the base outer surface and the base cavity, a fluid outlet passageway extending between the base outer surface and the base cavity, and a second pressure sensing passageway extending between the base outer surface and the base cavity. A valve element within the base and bonnet cavities controls a fluid flow path through the fluid inlet passageway and the fluid outlet passageway.
