Product Description

 

Our customized liquid silicone rubber umbrella valves, also known as one-way check valves, are versatile components widely used in various applications. These umbrella valves are commonly found in vessel vent valves for automotive fuel tanks, in-and outlet valves for pumps, one-way check valves in breathing masks, and many other fluid control functions in medical devices, home appliances, cars, and toys.

Umbrella valves are elastomeric components with a diaphragm-shaped sealing disk or an umbrella shape. They serve as essential sealing elements in backflow prevention devices, one-way valves, check valves, vent valves, pressure relief valves, and metering valves.
