The present invention relates to a pressure reducing valve comprises: a housing of which one end has an inlet and the other end has an outlet; a movable member installed inside the housing and at the outlet, having an inside communicating with the inlet and the outlet, and capable of being vertically moved inside the housing by a fluid flowing through the inlet; a fixed member installed inside the housing and at the inlet, and having a flow path communicating with the outlet; an elastic member installed inside the housing, and applying an elastic force to the movable member to be pressed toward the outlet; and a diaphragm having one end fixed to the inside of the housing, having the other end connected to the movable member, and preventing the fluid, which flows from through the inlet, from flowing to the elastic member, wherein the diaphragm is installed to prevent friction from being generated between the diaphragm and the peripheral parts thereof when the movable member is moved by the pressure of the fluid, thereby preventing the deterioration of a pressure reducing performance by preventing the deformation of the diaphragm or damage to the diaphragm. |
