As pressure or flow increases, the lips open further, allowing more flow. This feature allows solids to pass unhindered with low pressure loss. The rubber used on these valves provides continual corrosion resistance. The outer layers of Neoprene rubberrepel marine organisms which eliminates marine fouling issues. Our capabilities also include designing, assembling, and testing finished sub-assemblies, including Class VI thermoplastic housings with integral biocompatible elastomeric valves such as those found in:

The original Tideflex design, the TF-2, has a flare on the top and bottom of the valve. It has been superseded by the TF-1 and has been standardised by many consultants and owners. We require this information to understand your needs and provide you with a better service, and in particular for the following reasons: Neoprene is the best rubber for Ozone sunlight protection, and stops barnacle growth and sea weed build up. The TF-1 has become the preferred Tideflex configuration for outfalls. Designed for in-structure and end-of-pipe installations, the TF-1 features a flat bottom and flared top. This allows the valve to be installed at a lower overall elevation than other configurations, with less bottom clearance required. This is especially important in low-lying areas where maintaining as much driving head is critical, or where silt, sand and debris might tend to collect beneath the valve. 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. 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. 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.Depends on the hardness: generally, dispensing valve with high durometer & hardness will have better restoring forces. 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. This article needs additional citations for verification.
