The automatic control valve is a control valve that uses the energy of the medium itself to realize automatic regulation. It can adjust the pressure, temperature, flow rate and liquid level. It can work in the place of no electricity and no gas, so as to simplify the equipment and save energy. Applied in petroleum, petrochemical, electric power, metallurgy, food, machinery, building construction. Automatic control of pressure reduction and stabilization of various gases, liquids and vapors (used before or after valves).
