The slip on model, easily slips over the outside diameter of the pipe, and is clamped on with the clamp(s) supplied with the valve. This will securethe valve to the pipe.

Rubber material options available include Neoprene, EPDM, Viton, NBR, Natural Rubberfor manyapplications.

Molded Strip / Gaskets

The TF-1 can also be installed on the OD of elliptical pipe and many arch pipes. Tideflex Technologies also offers a thimble plate option allowing the slip-on TF-1 to be installed directly to a headwall or seawall. Depends on the die-cutting tool: It needs to be sharp enough, so that it can cut the silicone thoroughly to invoid diecutting burrs, and to invoid the situation of "slit" doesn't close well. Using a lubricant, it is recommended to lubricate the inside of the rubber where it will slide over the pipe end. This is to prevent the rubber from any damage during installation.

Position the valve in line with the pipe, lifting equipment may be required for large size models. The clamp(s) may need to be loosened for installation.

Ensure that the valve is installed in a vertical position, with the opening in a vertical up and down position. The TF-1 installs by slipping over the end of an exposed piece of pipe, and is fastened with compression clamps. The inside diameter of the TF-1’s cuff is fabricated to exactly match the outside diameter of the pipe.

Operation staffoperating techniques can also affect whether the slit can be cut well. Generally, the slit should be cut perfectly the first time. It will leave burrs if proceed second cutting. The design prevents logs or other floating objects from entering the valve closing mechanism, therefore the valve will always close when required to, no matter what the environment may throw at it. Depends on the permanent compression set value: for this dispensing valve, we use high-elastic FDA Food Grade silicone, so its restoring forces is good, the dispensing valve can close & open easily without the distortion situation. The engineered construction allows the valve to open with minimal pressure, and close against a rising tide with no requirement for a power source or manual operation. Ensure the flange specification is the same for both the valve and the pipe flange, so that they can be bolted up to each other.During the transportation process or the installation process, if workers did not deal well will cause surface damage. The flexibility of the Tideflex allows the valve to compress around trapped solids providing a much better seal than flap gates, as confirmed by the USEPA. With the development of the patented curved bill, sealing capabilities are even further improved because the curve bill is more flexible than the rest of the valve and therefore compress more around solids. The TF-1 allows installations in such structures and are easily retrofit to existing structures, often replacing failed flap gates, without the need for breaking up the concrete floor to provide bottom clearance.

Position the valve flange to line up with the pipe flange or headwall drilling pattern, keeping the valve in the vertical position. Lifting equipment will be required on large sizes. When inserting the valve into the end of the pipe, ensure that the valve is installed in a vertical position so that the valve outlet is going up and down, and not side to side. You may choose to restrict the collection or use of your personal information in the following ways: Ensure that the inside diameter of the pipe is measured, as the outside diameter of the valve needs to be slightly smaller so that it fits inside the pipe.We require this information to understand your needs and provide you with a better service, and in particular for the following reasons: Depends on the hardness: generally, dispensing valve with high durometer & hardness will have better restoring forces.
