Working principle and purpose of the product:

  Self operated micro pressure and differential pressure regulating valve is a type of valve that does not require external energy, uses the energy of the controlled medium itself as a power source, introduces the actuator membrane chamber to generate thrust, and controls the movement of the throttling element to achieve automatic regulation. Mainly used in various industrial furnace gas combustion systems to control the mixing ratio flow of fuel A and B, achieving ideal natural material conditions: used for pressure reduction, stabilization, and relief regulation of sealing oil and various industrial gases such as hydrogen, liquefied gas, oxygen, and nitrogen in hydrogen cooled generator sets; used for gas sealing of various oil, chemical, and liquid storage tanks.

Product Structure Features:

1. Self operated pressure regulating valves do not require external energy and can work in situations without electricity or gas, which is both convenient and energy-saving.

2. The pressure segmentation range is fine and intersecting with each other, with high adjustment accuracy.

3. The pressure setting value can be continuously set during operation.

4. Adjust the pressure behind the valve, with a ratio of 10:1 to 10:8 between the pressure before and after the valve

5. Adopting a pressure balance mechanism to make the regulating valve responsive and precise in control
