In-Line Insertable Check Valve – Series CVI

Fuller Valve Series CVI In-Line Check Valves are designed to fit right inside the pipe. No valve body is required.

This feature not only saves money but also permits installation in otherwise difficult situations such as tank outlets, floor drains, sewer interceptors, overflow systems, retention basins and manhole outlets.

Series CVI-E fits directly inside the pipe and is secured in place by an expandable clamp ring made of stainless steel.

Series CVI-F also fits directly inside the pipe and is bolted in place between the pipe flanges.

Note: Series CVI valves have increased pressure drop because the valve must be smaller to fit inside the pipe. Actual maximum flow area is less than 25% of nominal pipe area.
 

Available Elastomers

Standard construction utilizes a natural gum rubber inner tube reinforced with polyester cords with a multi-resistant Neoprene outer cover.

Neoprene is also commonly used for the inner tube in sewage applications.

Other elastomers are available but are not normally required for applications where this style of valve would be used.
