Introduction of self-operated temperature regulating valve
型自力式温度调节阀是由温度传感器与控制阀两部分组成,是一种无需外来能源,利用被控介质自身温度变化进行自动调节的节能产品。 ZZWP self-operated temperature 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 automatically adjusts the temperature change of the controlled medium. The product is suitable for automatic temperature control in various heat exchangers with various gases, steam, hot water, oil and other media. It has the advantages of wide temperature setting range, convenient adjustment, continuous temperature setting, over-temperature over-plant protection, and convenient temperature setting. Widely used in urban heating and heating systems and industrial sectors such as electricity, petroleum, metallurgy, pharmaceuticals, boilers.
