STZ Series
automatic thermostatic valve (back-water temperature control valve) is applicable for the
hot-water concentrated heatsupply system to set the temperature as desired and to
automatically adjust the temperature and flow of the hot water, thus to make the
heat-supply balanced.
Capable of overcoming the difficult problems of both horizontal
and vertical imbalances in the heat-supply system, it is especially suitable to be mounted
on each group of the radiator or each small district or each building of the buildings'
heat-supply system to automatically adjust the flow of the back-water, control the
temperature of heat-supply, simplify the system and save both energy and investment.
|
PRINCIPALE OF OPERATION: |

|
It consists of the
valve body, flap ( temperature-sensible component ),regulating screw etc. and with the
temperature-sensible component, several kinds of agents combined temperature-sensible
mixture is filled, such as the temperature-sensible agent, saturation agent, stabilizing
agent, filling agent and so on, of which the sensitivity to temperature and the
change-over of the heat-expansion and cold molding are used to drive the flap to move and
make the valve selfly adjust the degree of tension per the change of the temperature and
automatically close or open, thus to realize to automatically control the drainage
temperature and the flow adjustment. |
|
FEATURE PRODUCT: |

|
 |
Self-adjust the amount of the back-water without any external dynamic
force, saving expense. |
 |
Quick temperature sensing, gook sensitivity, high precision of temperature
controls. |
 |
Wide range of temperature adjustment and application, suitable for various
different states of working. |
 |
Small volume, low price and easy to mount and maintain. |
