V230W Self operated temperature regulating valveDetailed product description：

The V230W regulating valve is composed of a temperature sensor and a control valve. It is an energy-saving product that does not require external energy and uses the temperature changes of the controlled medium to automatically regulate. The product is suitable for automatic temperature control in various heat exchangers using various gases, steam, hot water, oil, and other media. The V230W regulating valve has the advantages of wide temperature setting range, easy adjustment, continuous temperature setting, over temperature and over trip protection, and convenient temperature setting. V230W regulating valves are widely used in urban heating, heating systems, and industrial sectors such as electricity, petroleum, metallurgy, pharmaceuticals, and boilers.
