Shanghai Metal Corporation is experienced manufacturer of control valve in China since 1980s. Control valves refer to process parameters such as medium flow rate, pressure, temperature, and liquid level used in the field of industrial automation process control. Based on control signals in the automation system, the valve opening is automatically adjusted to achieve the regulation of medium flow rate, pressure, temperature, and liquid level.
