Its concept is simple yet it offers exceptional back flow prevention with as little as 1" of head pressure to allow flow.

The ProFlex rubber check valves are manufactured completely of rubber with top quality fungicide and barnacle resistant rubber being selected for use. It is therefore impervious to the daily operational vulnerability affiliated with the water and sewage industry such as rust, freezing, corrosion and seizing often found in the check valve industry.

Benefits of the ProFlex rubber check valves include greatly reduced operational costs, prevention from animals or insects lodging or disturbing the flow of liquids from outfall pipes, easy opening which prevents flooding commonly associated with defective swing type valves and made in America from the same company you have grown to trust in providing you with products for your piping system requirements.
