FDA approved no drip silicone check valve

This kind of cross slit silicone check valves are mainly used for food and beverage dispensing, such as, sports water bottle, ketchup, mayonnaise, syrup or musturd sauces. Usually, it's made of food grade liquid silicone, processed by liquid injection molding, the cross slit size can be customized according to product viscocity. With over a decade in R&D for the punching process, we've achieved the automated production for cross slit punching, the daily capacity has increased from 50,000pcs to 200,000pcs per line, almost 4 times higher than before.
