V**0W
self-operated temperature control valve is composed of control
valve and thermostat.
According to the application, it divides into heating type and
cooling type. It is suitable for the non-corrosive liquid
,gas
and steam as well as the temperature control of various cooling
systems. When the controlled medium’s temperature is
higher, control valve will close (heating type); when the
controlled medium’s temperature is higher, control valve will
open (cooling type).
Main
features:
1
no external energy, effective energy saving
2 high control accuracy, stable operation, safe and reliable
3 temperature uniformity, the proportion of adjusting control
4 the temperature setting simple operation, convenient
adjustment
5 small volume, light weight, convenient installation

Structure and working principle
V**0W
self-operated temperature control valve: according to the
purposes with temperature control valve, can be divided
into cooling temperature valve and heating temperature valve, tee
mixing temperature valve and tee shunt temperature
valve. Different uses of self-operated control valve have the
same working principle. All are regulated by using
temp-response liquid ‘s heat expand cold shrink and liquid
incompressible character ,spring force overcomes spring
resistance, and push the plug downward, valve tend to be closed,
so that to reduce medium’s flow; whereas ,when the
controlled medium be lower than set value, temp-response liquid
shrink, spring return to open the plug, increase thermal
mass media flow, make the controlled medium temperature be
higher. Recycle, so that the controlled medium temperature
keeps in the set temperature’s allowable range.
