UP100 10 Pieces Black Silicone Duckbill Valve One-Way Check Valve 25.5 x 17 x 24.5 MM for Liquid and Gas Backflow Prevent

Product Information

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. Crane BS&U has no direct influence on, or take any responsibility for any working practices employed or depicted in any image(s). Viking Johnson (part of Crane BS&U) manufactures couplings, flange adaptors and associated fittings for the Utilities industries. Viking Johnson cannot make recommendations regarding the pipeline design, which includes all components, intended operational substances, introduced chemical species and materials. Any comments made by Viking Johnson regarding product compatibility apply only to Viking Johnson's product range. 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. Rubber material options available include Neoprene, EPDM, Viton, NBR, Natural Rubberfor manyapplications.

As pressure or flow increases, the lips open further, allowing more flow. This feature allows solids to pass unhindered with low pressure loss. Neoprene is the best rubber for Ozone sunlight protection, and stops barnacle growth and sea weed build up. Ensure that the valve is installed in a vertical position, with the opening in a vertical up and down position. 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.Mass Productiom: Compression molding or liquid silicone rubber (LSR) injection molding, slit die cutting 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. There are no mechanical parts that can freeze, corrode, bind, or otherwise inhibit smooth operation. Ensure that the valve is installed in a vertical position, with the opening in a vertical up and and down position. This is how the valve works best. We require this information to understand your needs and provide you with a better service, and in particular for the following reasons:

The rubber used on these valves provides continual corrosion resistance. The outer layers of Neoprene rubberrepel marine organisms which eliminates marine fouling issues.Measure the section of the valve that will fit onto the pipe, and mark on the pipe with a permanent marker a line where the valve will slide up to. This will ensure the valve is secured on at the right location.
