First, the self-pressure regulator valve Overview
 ZZYP-type self-pressure regulator valve is a need without additional energy, the use of the controlled media its own energy as a power source, the introduction of the executive chamber~produce thrust~control the throttle element movement~automatically adjust. With measurement, implementation, control of the integrated features. Available in no gas, no electricity place. Widely used in petroleum, chemical, power plants, light industry, printing and dyeing industry, automatic control system for a variety of equipment, gas, liquid and steam media deceleration pressure, regulator (for the valve pressure regulator) relief pressure, Pressure control) automatic control. According~the user's different conditions can choose different spool structure and different implementing agencies, in order~achieve the best control effect.
 

Second, self-pressure regulator valve model

Pressure closed type: for the valve pressure regulator, when the valve pressure increases, the valve closed, in order~achieve decompression, the purpose of regulating. 
 Pressure type: for the valve pressure regulator, when the valve pressure increases, the valve opens, in order~achieve pressure relief, the purpose of regulating. 

 Third, self-pressure regulating valve main technical parameters

Note: The pressure of the sub-range can be designed according~user requirements. 
 
 Fourth, self-pressure regulator valve main performance indicators
 

 Fifth, self-pressure regulating valve can be equipped with an adapter
 condenser (for media for steam occasions), heat sink, etc.
