Series of Electromagnetism Valves and Negatively Charged Ion Generador   The electromagnetism valve is on the basis of absorbing overseas advanced technology and adopts top quality Al material, research and develop the new successful product. The capability and varies of technical indexes have reached the foreign advanced level.   It applies to the direction of flow for auto in the system of putting through, shutting off or transition the medium, and also used in auto-control and protect the loop.   Technical specifications: 1. the valves work normally under 85%～110% rated pressure 2.The Maximum working pressure is 3.5 Mpa; 3.Allowed temperature of valve medium: -20℃～＋120℃,relative humidity <95%     The design of circuit in FL-1 type of negatively charged ion generator is reasonable, novel and practical. the shoot pole adopt novel cooductive fiber as material, design as opening-uo electrode, the structure is advanced, the concentration of negatively cgarged ion generatou is high, while the concentration of ozone is low. It is widely used in health-type air-conditioner, cold-warm wind machinery,electric fan and so on.   Main technical parameters 1、rated working voltage:220VAC 50Hz 2、power:1W 3、The working surroundings:-5℃~+65℃ 4、Insulative resistance 5、Outputing voltage 6、Temperature rise<45k （surroundings temperature 25℃） 7、The concentration of negatively charged ion generator>4x106 /cm3 （30cm away form the end of shoot） 8、The concentration of ozone<0.06mg/m3 （30cm away from the end of shoot）     Frost Valve: It is sealed with stainless steel balls with direct-driving and closed structure and has many features as its safety, high temperatures resistance, high working pressure long life service, small size, etc... It ap- plies to the defrosting and other uses of system as refrigerators. air-cond- itioners, damp removers, ice-makers and so on.       Environmental Protect Type Food Rubbish Processor: The Food Rubbish Processor is a new-type indispensable environmental product for family kitchen in the prensent age. It is installed in the bottom of washing trough, which is the way out of the water. It can effectively crush varies of food, such as the bone of big, chicken, eggshell, hust of the melon and stone, ort and leftover, and whet it into starchiness granule, then vent it along with water via pipeline, thus can clean environment and eliminate peculiar.
