Product Description

Customized Liquid Silicone Rubber Umbrella Valves/One Way Check Valves

Silicone umbrella valve is widely used, their applications include vessel vent valves such as for automotive fuel tanks, in-and outletvalves for piston- and diaphragm pumps, one-way check valves in (disposable) breathing masks, and numerous other fluid control functions inmedical devices, home appliances, cars and toys.

Umbrella valves are elastomeric valve components that have a diaphragm shaped sealing disk or an umbrellashape if you like.These elastomericcomponents are used as sealing elements in backflow prevention devices or one-way valves or check valves, in vent valves or pressure relief valves and in metering valves. 

Product advantages:

1. 100% all rubber or silica gel structure, which can meet various high temperature resistance requirements
(depending on actual needs, different materials can be selected).

2. Material is environmentally friendly.

3. It is not blocked, sealed, and effectively prevents liquid and gas from flowing back.

4, long service life, no failure.

5, the opening pressure is small, generally into the liquid or gas of 1-5KPA pressure, it can be opened.

6, easy to install

Silicone rubber umbrella valve benefits include:

*Strengthen sealing

*Position independent

*Variable opening pressure trough seat thickness

*Corrosion resistant, chemical resistant;Wear resistance and aging resistance
