One-way Valves

One-way valve components are used to create a unidirectional flow in a device. 
They are in fact elastomeric sealing elements that allow forward flow and prevent backflow. 
There are different designs.
(1)If you like low opening pressure and ease of assembly then the first choice would be a duckbill valve. 
(2)If you need a certain cracking pressure or a low-pressure drop at higher flows then would be an umbrella valve.



One-way alves are used to facilitate a unidirectional flow of fluid. 
Depending upon the application this either causes a forward flow or preventsbackflow in a device. 
Our flapper, umbrella, duckbill and custom valves are produced from a wide variety of rubber compounds,including medical and 
food-grade silicone and hydrocarbon-resistant fluoro silicone
rubber in order to handle a broad range of tolerances and temperatures.


All one-way rubber sealing valves allow fluid, either a liquid or a gas, to flow through it in only one direction. 
The design and structure of one-way check valves make them widely applicable in pressured fluid environments. 
The elastomeric compound offers itself to be low-maintenance, rust-free, and highly responsive to very subtle pressure changes


Flapper Valves accomplish this by containing a hinged flap or disk that swings in one direction only. 
Umbrella Valves feature a ball or rounded shaped end which snaps easily into a mating plate or receptacle. 
Duckbill Valves allow positive pressure to open the valve and negative pressure to close off flow. 

Our custom one-way rubber valves offer a solution to unconventional unidirectional flow requirements.
