Beschreibung
Zusammenfassung:	A fluid regulating device includes a regulator valve (12) having an inlet (14), an outlet (16), and a valve port (18) disposed between the inlet (14) and the outlet (16). An actuator (20) is coupled to the regulator valve (12) and includes a valve disc (22) that displaces between a closed position and an open position. The device also includes an overpressure protection device (25) adapted to stop flow from the inlet to the outlet when pressure in a control cavity reaches a predetermined level. The overpressure protection device (25) includes a sensing tube (28) having a first end (29) in fluid communication with the control cavity (27) and a second end (30) in fluid communication with the outlet (16). The sensing tube (28) has a first portion extending parallel to the flow axis. One or more apertures (34) are disposed in the sensing tube (28) adjacent to the second end (30), and each of the apertures (34) has a centerline that is perpendicular to the flow axis.
