A pressure regulating system is provided. The system comprises a valve (2', 4') including a valve inlet (13') and a valve outlet (15'), a regulating piston (16) positioned in a fluid pathway between the valve inlet and the valve outlet, a chamber (12') in fluid communication with the regulating piston, a pressure setting valve (14') in fluid communication with the chamber, a solenoid valve (24') in fluid communication with the chamber and a sense line fluidly (20') communicating with the valve inlet with the solenoid valve. The pressure setting valve is configured to vent gas to an ambient environment when a pressure within the chamber exceeds a threshold value. The solenoid valve is configured to move from a first position to a second position, the first position fluidly connecting the chamber with the sense line, and the second position fluidly connecting the chamber to the ambient environment (and thereby disconnecting the sense line from the chamber).
