A fluid pressure controller has an air supply valve plug displaceable under an action of pilot pressure of a pilot chamber. When the air supply valve plug is seated on a seat section, fluid communication between a supply port and a regulator port is interrupted. Further, the fluid pressure controller has a solenoid valve. When electric power supply to the solenoid valve is interrupted, the solenoid valve is opened to generate pilot pressure applied to the air supply valve plug by the original pressure of pressurized fluid introduced from the pressurized fluid supply source to the supply port. |
