Our silicone valves can be universally applied in many different applications, whether in the health care, automotive, appliance or food and packaging industries. Silicone valves include umbrella valves, duckbill valves,membrane valves, flapper valves and diaphragm valves, etc.Silicone Rubber Umbrella/Duckbill/Check/Flapper/Die-cutting ValvesSilicone Rubber Check Valves, are also calledone way valves, non-return valves, air flow valve, which are one popular type of silicone rubber one way valve, used in air control device or liquid & water flow controllers like medical tubing or pip air pressure controllers device, diving equipment, toilet products, outlet valves, automotive fuel tanks etc.Umbrella ValvesSilicone Umbrella Valves, known as Mushroom Valves or Umbrella Check Valves. Rubber Umbrella Valves have round diaphragm seals & seat for air or water pressure relief and backflow controls. The stem and hooks of umbrella valve is for fixing. Umbrella valves are generally made from medical grade or food garde silicone or LSR materials. Other rubber materials like EPDM, NBR etc. are available in our company.Duckbill ValvesDuckbill Vallve, as a elastomeric fluid-flow control components, seals or nozzles, is one type of rubber one way valves. The duckbill design aim to automatically prevent air or fluid backflow and allow forward flow.
