Self-operated control valve

Self‑operated control valve relies on the energy of the medium itself (pressure, temperature, flow) to realize automatic regulation without external power supply such as electricity or compressed air.

It is used to control pressure, temperature and flow rate of water, steam, gas and oil, widely applied in heating systems, oil & gas, chemical industry and pipeline stations.

Simple structure, energy‑saving and easy maintenance.

Working Principle:
It senses changes of medium parameters through the sensing element, and drives the valve core to adjust opening by medium pressure, so as to stabilize pressure, temperature or flow automatically.
