Abstract
A pressure control valve equipped with a solenoid valve, in which a main valve body is provided with an air-supply chamber connected to a pressurized air source, a control pressure chamber into which pilot pressure is input, an output chamber connected to an air-pressure apparatus, and an air-supply valve which establishes contact between and isolates such air-supply chamber and such output chamber. Such pressure control valve further includes a pressure-adjusting piston which is urged one way by a pressure-adjusting spring and is urged the other way by such pilot pressure of such control pressure chamber, and a hollow exhaust valve rod is provided integrally with such pressure-adjusting piston to open or close such air-supply valve in accordance with such pilot pressure; and in which such solenoid valve supplying such pilot pressure to such control pressure chamber is attached to such main valve body. Such pressure control valve is characterized in that such valve body of such solenoid valve is fitted in one of an upper surface and a lower surface of such valve main body, in a position in which it is adjacent to such exhaust valve rod.
