Message: | 3/4inch brass 2 ways frost valveBody material: BrassMax. working pressure: 10 barAmbient temperature range: -30–90°COpening temperature: 4°CClosing temperature: 8°CAccuracy: ±2°CConnections: G3/4" or NPT3/4" , one inlet – male thread , one outlet – male threadNet weight: 0.14 KGSGross weight: 0.15 KGS When the water temperature below 8℃. This causes the sensor to move and open a tiny passage so that water can drain out, this prevents water from freezing inside the pipe. When the temperature below 4 ℃,the valve opened completely. The water will be flow out from the solar panel . When the temperature above 8℃, the valve will be closed. Before installing the device, make sure that the system has been flushed and cleaned to remove any traces of dirt that may have accumulated during installation. The frost valve outlet port must vertical to ground, so as to permit a free and unrestricted downward flow of the water as it drains out. The device must be installed in the points of the circuit at risk of freezing so that the water may flow freely and in order to prevent pipes, storages or components located upstream of the device from freezing. Pipes downstream of the device must be protected from frost if, due to the intervention of the device, the water contained in them remains stagnant without flowing. In the case of exposed outdoor pipes, the installation of a suitable heating cable will provide effective protection. 1. small carton (mm) : 150*87*52 , 7 pieces antifreeze valve in one small carton .2. big carton (mm) : 470*325*190 , 210 pieces antifreeze valve in big carton .3.
