Self-operated micro-pressure control valve consists of actuator and control valve. The vale uses the pressure of medium as its power source to realize automatic control without the help of foreign energy. Accuracy of self-operated micro-pressure control valve is higher than general self-operated control valve by one time. It is suitable for the situations which need higher accuracy. It is widely utilized in chemical industry, metallurgy, petroleum, pharmacy, etc.
