ZZWP self operated temperature control valve temperature sensor DN125 heating temperature control valve cast steel stainless steel carbon steel




ZZWP self operated temperature control valve YZW hot and cold water, steam temperature control valve heating steel sensor


YZW self operated temperature control valve according to the change of the controlled medium temperature automatic control valve, without external energy and automatically adjust the temperature, suitable for steam, hot water, hot oil as medium heat a variety of occasions. Widely used in heating and air conditioning, hot water, electric power, petrochemical, machinery, textile, rubber, food and other industries.
Working principle
YZW self regulating valve using the principle of thermal expansion of liquids and liquid can not be compressed to achieve the automatic adjustment. Expansion of the liquid temperature sensor is uniform, the control effect of proportional control. Charged medium temperature sensor, the temperature sensing liquid in volume with the expansion or contraction. The controlled medium temperature is higher than the set value, temperature of liquid expansion, pushing the valve shut down valve, reduce the flow of heat medium; the temperature of the controlled medium is lower than the set value, temperature of liquid contraction, reset spring to push open the valve core to increase the flow of heating medium.
aHydraulic drive, without external power supply, the use of safe and reliable.
bA new temperature control, medium selection, thermal expansion ratio characteristics, strong stability.
cLow cost, stable operation, wide temperature range.
eBalance valve, such as the percentage of/Linear flow characteristic.
fCompact structure, small volume, simple installation,Long service life.
