Regulating valve, also known as control valve, is the final control element in the field of industrial automation process control by receiving control signals output by the regulating control unit and using power operation to change process parameters such as medium flow rate, pressure, temperature, and liquid level. It's suitable for air, water, steam, various corrosive medium, mud, oil and other medium. It can be applied in civil systems such as electricity, chemical industry, air conditioning, heating, ventilation, metallurgy, environmental protection, water treatment, light industry, domestic hot water, and industrial automation systems such as building materials.
