徴とする減圧弁。 The fluid pressure flowing out from the primary flow path to the secondary flow path is adjusted by displacement of the main valve interposed between the primary flow path and the secondary flow path, and the pressure of the fluid flowing out from the primary flow path to the secondary flow path is adjusted. A pressure reducing valve in which increased fluid pressure in a downstream flow path is discharged to the outside from an exhaust port, the main valve having a relief hole that communicates the secondary flow path and the exhaust port, A main valve diaphragm that receives fluid pressure in the secondary flow path on one side is removably abutted on the main valve to close the relief hole, and is also energized by the increased fluid pressure in the secondary flow path. The pressure reducing valve is characterized in that the relief hole is opened by separating from the main valve.
