will initiate flow when the thermostatic actuator senses 35°F (1.6°C) and will remain open as long as the discharge water temperature is below 40°F (4.4°C). In standard flow, the actuator will sense ambient temperature to initiate flow and then respond to water temperature; in reverse flow, the actuator will sense water temperature.
Typical application
Depending on the temperature sensing element of the thermal actuator, the control opens the valve.
Freezing protection to prevent human error or partial rupture of the valve blocked.
This causes a lot of freezing damage each year, causing huge economic losses, including repairs to damaged equipment, pipes, and system outages.
As shown in the figure above, the water in the pipeline above the ground (sections A to B) continues to lose heat to the environment at -15°C until it is frozen (if the water is not flowing).Assuming that the water at point B is at 4°C, the valve is slightly opened and 8°C of water from the underground main pipe flows out along the pipe above the ground.If the water flow is suitable, the water temperature in the pipeline will drop, but the temperature will not be lower than 4°C when flowing out from point B.If the ambient temperature continues to drop or a strong wind blows through, the valve at point B must be opened further to increase the flow of water so that the temperature does not fall below 4°C when the water flows out of the valve.
Pipeline antifreeze valve eliminates the human errors associated with manual valves. This automatic valve is ideal for the protection of piping, safety showers, solar collectors & piping, condensate systems, fire lines, spray nozzles, or as backup protection on traced systems.
