Electric thermostat valve

Product Description YZW type Self-temperature control valve without external energy and automatically adjust the temperature. It is suitable for steam, hot water, hot oil heat exchangers for a variety of occasions media. Widely used in heating, air conditioning, domestic hot water temperature is automatically adjusted, and the temperature is automatically adjusted for special occasions, such as chemical, textile, pharmaceutical and other production engineering. It works Self-operated temperature control valve using a liquid thermal expansion and incompressible liquid principle automatic adjustment. Expansion of the liquid temperature sensor inside the uniform, the control action is a proportional adjustment. When accused of medium temperature, temperature of liquid volume in the sensor with the expansion or contraction. When accused of medium temperature higher than the set value, the temperature of liquid expansion, pushing down the valve to close the valve, reducing the flow of heat medium; temperature controlled medium is less than the set value, the temperature of liquid contraction, promote the return spring Open the valve to increase the flow of heat medium. Scope heating and air conditioning, hot water, petrochemical, power, machinery, textile, rubber and food industries.
