A regulator device includes a first valve member and a second valve member disposed within a housing of the device. The first valve member regulates the pressure of fluid exiting the device, and the second valve member is biased to a closed position and is opened by manipulation of an actuator. A sealing element is connected at the housing outlet and has a transverse cross-sectional dimension that decreases from an inlet of the sealing element to an outlet of the sealing element. In addition, a guard is provided that extends around a periphery of the actuator and includes a cut-out section to permit easy access to the actuator during use of the device.
