Antifreeze Valve

high quality antifreeze valve for solar system in winter

Winning Thermo Control Equipment Co., Ltd designs and manufactures self-operating

temperature actuated freeze protection valve. When the temperature approaches freezing, the valve opens to discharge the cold water and re-closes upon warmer water replacement. This cycle continues preventing panel and piping freeze up.

The Freeze Protection Valve are widely used in solar energy, air pumps, eyewash, emergency shower, saloon car, water system, high way water system, ship, yacht and so on.

          * Brass body and thermal element

          * Narrow temperature band

          * Compact, low mass - Fast response

          * Ram-type plug for reliable tight shutoff

          * Sensitive to temperature only

          * Unaffected by pressure variations

          * Easy installation with pipe wrench

          * Discharges the minimum amount of water required to prevent freeze damage

The Freeze Protection Valves utilize a reliable self-contained thermo element which is sensitive

to temperature and operates without any electrical power or air pressure. When the fluid temperature approaches freezing, and freeze damage is imminent, the thermal actuator modulates the valve open. When the makeup water temperature returns to the safe range, the valve then modulates closed, minimizing water loss. Due to the actuator’s placement in the fl uid stream, this valve is unaffected by ambient air temperature, and opens only when the water is in danger of freezing, being open at 1℃, and closed at 4℃. This cycle will repeat as often as necessary to help prevent freezing.

Freeze Protection Valve Application Considerations

1. The Winning "Freeze Protection Vavle(s)" functions properly provided the valve is installed

in a location, where during operation, the warmer supply water first passes through the collectors and/or pipe to be protected and then through the valve. The valve should be located in a position to allow good water distribution through the solar panel so that when the valve opens, water fl ows as evenly as possibe through all the collector tubes. Location of the valve may vary depending on the system design and piping.

2. Select a mounting position where the valve will sense the coldest anticipated ambient temperature. Do not insulated the valve. Do not install valve near an external heat source.

3. The "Freeze Protection Valve (s)" should be installed in a vertical position with discharge port

down.

4. If the discharge tube is used, make sure it will drain freely and is installed in accordance to local codes. Avoid water traps in the discharge tube that could freeze and prevent drainage.
