特徴とする定圧制御バルブ。 A valve that is connected to the discharge side of a pump to control the pressure of fluid at a constant pressure, and includes a valve body having an inlet channel and a discharge channel, and a valve body that is slidably housed within the valve body and controls the pressure of the discharge channel. and a control valve body having a balance piston disposed on the opposite side of the throttle valve via a valve stem, and a control valve body having a balance piston located between the throttle valve and the balance piston on the opposite side of the throttle valve. a pressure regulating device that supplies fluid to the balance piston, causes a small flow of pressure fluid to flow into a piston chamber on one side of the piston through a small hole provided in the balance piston, and adjusts the pressure in this piston chamber to a constant level. The sliding direction of the control valve body is formed coaxially with the inlet waterway of the main body, a discharge waterway is provided in a direction perpendicular to the inlet waterway, and the other end is coaxial with the inlet waterway. A constant pressure control valve, characterized in that an opening is provided through which the control valve body is inserted, and the opening is closed with a lid that can be opened and closed.
