レータ。[Claims for Utility Model Registration] 1. An electropneumatic regulator that converts electrical signals into air pressure, which comprises a main valve that switches the flow of air pressure, a diaphragm valve mechanism that controls the operation of the main valve, and a diaphragm valve mechanism that controls the operation of the main valve. A high-speed and highly durable air supply two-way solenoid valve and an exhaust two-way solenoid valve supply and discharge primary side pressure to and from the pilot chamber of the diaphragm valve mechanism, respectively, and a secondary side pressure of the main valve. A pressure sensor to detect,
When the secondary pressure detected by this pressure sensor deviates from the set pressure, the two-way solenoid valve for air supply or the two-way solenoid valve for exhaust is operated by the difference between the detected pressure and the set pressure. It comprises a pressure control means for supplying or discharging air pressure to or from a pilot chamber of a diaphragm valve mechanism, and is characterized in that a throttling means is provided downstream of a communication portion of the pressure sensor to the secondary side of the main valve. Electropneumatic regulator. 2. The electropneumatic regulator according to claim 1, wherein the throttle means has a smaller cross-sectional area than an effective cross-sectional area on the secondary side of the main valve. 3. The electropneumatic regulator according to claim 2, wherein the ratio of the effective cross-sectional area S1 of the secondary side of the main valve to the cross-sectional area S2 of the throttle means is about 1:0.7.
