Rubber valves are used in a variety of applications. Valves are devices, available in various shapes and sizes, designed to meter, maintain or restrict the flow of materials through hoses, pipes, tubing or entire systems. Valves generally work by allowing flow while they are in their open position, and restrict flow when they are closed.
There are wide varieties of rubber valves like check valves, ball valves, air pressure valves, butterfly valves, gate valves etc. A very common application of rubber valves is in tires and tubes to check air pressure. Rubber is used to design valves so as to allow one way sealing devices like as duckbill valves, umbrella valves, flapper valves etc. to withstand harsh chemical environments. The right valve design as per flow parameters can be produced by using rubber.
