This series of brine valves have overcome the deficiency of the products existing in the market. It can not only protect water injection and check the air, but also can limit the extreme amount of water injection and filter the water running inside. If water injection is too fast, the liquid level inside the brine well will spill out quickly and the injection has to be shut down, which will result in the insufficiency of water inside the brine tank and have bad influence upon the outcome of recycling. This kind of brine valves depends on water pressure to work. It is reliable in working and valuable in extensive employment.
