Self pressure regulating valve without any external energy, can in no electricity and no gas in the place of work, both for the convenience and save energy. The pressure range and cross section thin, high accuracy of regulation. Pressure set value during operation can be continuous set. Adjustment of the valve after the pressure, the valve before the pressure and valve after the pressure ratio of 10:1 to 10:8. The rubber diaphragm actuator detection, high measurement accuracy, sensitive action. The pressure balance mechanism, so that the valve is sensitive, accurate control.
