Self-operated regulating valve

Self‑operated regulating valve uses the pressure, temperature or flow energy of the medium itself as power, requiring no external electricity or compressed air.

It automatically stabilizes pressure, temperature or flow rate of steam, water, gas and oil.

Widely used in heating, petrochemical, oil‑gas, pharmaceutical and water supply systems, with simple structure, energy‑saving and easy maintenance.

Working Principle:
The sensing element detects parameter changes of the medium, and drives the valve plug to adjust opening by medium pressure, realizing automatic closed‑loop regulation.
