Features Quiet operation - Non slamming - Minimal maintenance - Seals around trapped objects - Low head loss - Reliable performance


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 and waste water applications.

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

Flanges and Backing Rings

Flat faced, reinforced rubber flanges with metal backing rings are drilled in accordance with customer specifications.

In addition to piping industry standards, unique dimensions and shapes of flanges are also available.

Flange backing rings are available in galvanized steel or painted steel and stainless steels depending on the application. Fuller Valve recommends stainless steel backing rings.

Larger diameter valves are supplied with a lifting clevis to assist the installation of the valve. The same clevis can be used to support the valve and water weight.
