Non Return Valve
Non Return Valve, also callen ,  One Way Valve & Check Valves, is a elastic diaphragms or sealing gasket used in pressure relief valves as controller device or flow control devices.
Non Return Valve, its diaphragm can be used in low or high pressure systems to control or limit the air or liquid water with valves.

Non Return Valves include many shapes according to designs and appliances like: Duckbill Valves, Cross Slit Valves, Dispensing Valve, Air Control One Way Valve, Flange Valves, etc.

Xiamen Better Silicone Company can make compression mold tooling, liquid silicone rubber injection molding ( LSR Molding) and produce different shapes translucent elastomeric silicone rubber sealing valves & Gasket in the 0.1 mm thickness range according to customer's designs drawings, samples or ideas etc.
 

Non Return Valves are unique and one-piece silicone rubber components that act as backflow prevention devices, check valves and elastic lips to prevent backflow or allow forward flows.
Non Return Valve is also called check valve or one way valve, which needs to be punched by die tooling after silicone rubber compression molding or LSR injection production. This process is the key to one way check valves quality. 
Non Return Valve not only takes full advantage of elastomeric silicone physical properties, but  also make the most of die or slitting cutting application. Generally, check valves hardness, cutting area and slit cutting technology all are keys to non return valve quality.
Non Return Valves have a wider range of application than umbrella valves because of good controller functions for air and liquid fluid.
