Self-operated differential pressure control valve

Self‑operated differential pressure control valve automatically maintains stable pressure difference between two pipelines by using the medium’s own energy, without external power supply.

It is widely used in heating systems, central air‑conditioning, water supply and drainage, chemical and petrochemical industries to balance system pressure difference, prevent flow fluctuation and ensure safe and stable operation of pipelines and equipment.

Working Principle:
The valve detects pressure difference changes through the sensing unit, and drives the valve plug to adjust opening automatically, so as to keep the differential pressure constant.
