AR, BR series pressure regulating valve is the pressure regulating component in the compressed air processing component. It can adjust the 1MPA compressed air delivered from the air compressor to 0～0.85MPA to meet the needs of the equipment. The pressure regulating valve is also called: reduction Pressure valve, pressure reducer, pressure regulator, instrument air pressure reducer, compressed air pressure regulator. The specific working principle is also very simple: use the elastic force of the spring to drive the diaphragm against the opening of the inlet hole, and the elastic force of the spring can be adjusted by the knob. According to the principle of pressure balance, when the upward force of the spring is just equal to the gas in the inlet hole When the force is applied to the diaphragm, the pressure balances. This is the equilibrium state of the diaphragm in opening and closing, that is, the air pressure of the air is equal to the average pressure generated by the spring pressure, which is equivalent to using the principle of the spring to control the air pressure. value
