What Is Medical Silicone Valve ?

Medical silicone valve is also called medical one way valve, made of medical grade liquid silicone material, processed by LSR injection molding, can be used for medical equipment, such as: infusion and injection. Medical silicone valves have high temperature resistance, non-toxic and odorless features, which can ensure the safety and hygiene. At same time, medical silicone valves also have good sealing performance and fluid control capabilities, which can effectively control flow and pressure and improve the accuracy and safety of medical operations.
