Self-operated pressure regulating valve

Overview:

Self-operated pressure regulating valves are a type of valve that does not require external energy sources (such as power or air sources) and achieves automatic regulation by relying on the energy of its own medium. This product can operate in environments without electricity or gas, featuring a quick-opening flow characteristic and sensitive operation. It is widely used in the automatic control systems of various equipment in the petroleum, chemical, power station, light industry, printing and dyeing industries, etc., for the pressure stabilization and automatic control of gas, liquid and steam media.
