とする圧力制御弁。 A valve body with a valve that can be opened and closed;
A regulator that generates control pressure by reducing the upstream pressure introduced from the upstream side of the valve body, and the control pressure generated by this regulator, the downstream pressure introduced from the downstream side of the valve body, and the spring biasing force of the main spring. It is composed of a combination of elements of a mount roller that oppose each other via a diaphragm and open and close the valve according to the balanced position of the diaphragm,
The regulator includes a metering valve that throttles air introduced from the upstream side of the valve body to lower the pressure and generate a control pressure, and a vacuum bellows that pulls the metering valve in its opening direction in proportion to ambient pressure. , a plurality of stages of diaphragms with different pressure-receiving areas that pull the metering valve in the closing direction in response to the control pressure generated by the metering valve, and a control spring that biases the metering valve in the opening direction. What is claimed is: 1. A pressure control valve comprising: a control pressure switching mechanism for switching a sensing state of the control pressure for a plurality of stages of the diaphragms having different pressure receiving areas.
