The self-operated pressure regulating valve adopts a fast-opening flow characteristic and has the advantages of sensitive operation, good sealing performance, and small pressure setting point fluctuation. The self-operated pressure regulating valve is widely used in various industrial equipment such as petroleum, chemical, power, and mechanical manufacturing for automatic control of gas, liquid, and steam media for pressure reduction, stabilization, or pressure relief and stabilization. The self-operated pressure regulating valve does not require an external energy source. It uses the energy of the regulated medium as the power source to introduce the actuator to control the valve core position, change the pressure difference and flow at both ends, and stabilize the pressure before (or after) the valve. According to different working conditions of users, different valve core structure types and different actuators can be selected to achieve better control effects.
● No additional energy is required. It can operate in areas without electricity or gas, which is both convenient and energy-saving.
● The pressure segmentation range is finely divided and interlocks with each other, resulting in high adjustment accuracy.
● For pressure regulation after the valve, the ratio of the pressure before the valve to the pressure after the valve can be 10:1 to 10:8.
● Anti-low-leakage design packing and packing case
● Rubber diaphragm type detection, with high measurement accuracy and sensitive operation of the actuator.
● By adopting a pressure balancing mechanism, the regulating valve becomes highly responsive and precise in control.
