ZZWP self-operated temperature control valve is composed of temperature sensor and control valve. It is a kind of energy-saving product which can automatically adjust the temperature of controlled medium without external energy. The product is suitable for automatic temperature control in various heat exchangers with various gases, steam, hot water, oil and so on. Wide range, easy to adjust, continuous temperature setting, over-temperature protection, temperature setting convenience and other advantages. Widely used in urban heating, heating systems and power, oil, metallurgy, pharmaceutical, boilers and other industrial sectors.


Product features of self operated temperature control valves


The valve does not need external energy, such as electricity or compressed air, safe and reliable. Temperature sensitive liquid expansion uniform, proportional regulation control, high control precision, stable work, effective energy saving, balanced valve body design, so that the valve can work under greater pressure difference, linear or equal 100 specific flow characteristics, temperature setting operation simple and convenient, small size, light weight, installation It is convenient.


Working principle of self operated temperature control valve


Self-operated temperature control valve can be divided into heating type, cooling type, confluence (shunt) temperature control type. It is regulated by the principle of thermal expansion of sensitive liquid, cold shrinkage and liquid incompressibility. The temperature sensor is inserted into the medium which needs to control temperature, and when the temperature of the medium rises, the temperature sensitive liquid is heated. The body expands, the force overcomes the spring resistance, pushes the valve core downward displacement, the valve tends to close state, thus reducing the flow of heat medium; otherwise, when the medium temperature is lower than the set temperature, the temperature sensitive liquid shrinks, the reset spring pushes the valve core open state, increases the flow rate of heat medium, so that the temperature of the controlled medium tends to rise. Thus the temperature of the controlled medium is always kept within the allowed temperature.
