When the water temperature below 8℃, the frost valve automatically opens so that a minimum quantity of water may flow toward the drain, enabling a small continuous inflow of water; this prevents water from freezing inside the pipe. When the water temperature increases to above 8℃ , the opposite action occurs, causing the device to shut off . when the water temperature below 4℃ ,the frost valve opened completely . 1. Country of origin : Shenyang of China2. Date of delivery : spot or production time 5-45 days .3. Production capacity : 5000 pieces every month .4. Port of shipment : the nearest sea port is DALIAN , the nearest air port is SHENYANG .5. Payment term : spot goods :100%TT , customized products : 30% in advance before production , 70% balance before delivery all the goods .6. MOQ : 200 pieces7. Warranty : free warranty in 3 years .
