Abstract
A pressure regulating valve including an actuator and a valve body. Communicating passages are arranged between a chamber of the valve body and a chamber of the actuator. Further, a pressure tapping tube is disposed in the chamber of the valve body. One end of the pressure tapping tube is connected to the communicating passage and the other end of the pressure tapping tube is suspended. By adopting this pressure tapping structure in the pressure regulating valve, the performance of the pressure regulating valve in a flow accuracy range is improved.
