Abstract
Fluid regulators are described. An example fluid regulator described herein includes a regulator body defining a sensing chamber between an inlet and an outlet, a bonnet coupled to the regulator body, the bonnet defining a loading chamber, the loading chamber being fluidly isolated from the sensing chamber and an environment surrounding the fluid regulator, a guide disposed between the sensing chamber and the loading chamber, the guide defining a vent flow path, the vent flow path to enable the sensing chamber to vent to the environment during a failure condition of the fluid regulator, a transverse bore defined between an interior surface of the regulator body and an exterior surface of the regulator body, the transverse bore being aligned with the vent flow path to enable fluid communication between the transverse bore, the vent flow path, and the environment surrounding the fluid regulator, the exterior surface of the regulator body defining a groove that is partially defined by the transverse bore, and a filter to be disposed in the groove to cover an outlet of the transverse bore.
