[Valve features]
Automatic control valve is the use of the media's own energy to achieve automatic control valve, the pressure, temperature, flow, level adjustment, in the absence of electricity, gas free place, to simplify equipment, save energy.
[Adaptive condition]
Used in petroleum, petrochemical, power, metallurgy, food, machinery, building construction. Automatic control of various gases, liquids, and vapors, reduced and regulated (for front or rear valves).
