We require this information to understand your needs and provide you with a better service, and in particular for the following reasons: 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. 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. 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 It has been superseded by the TF-1 and has been standardised by many consultants and owners.
There are no mechanical parts that can freeze, corrode, bind, or otherwise inhibit smooth operation. Depends on the hardness: generally, dispensing valve with high durometer & hardness will have better restoring forces. This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. 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. As pressure or flow increases, the lips open further, allowing more flow. This feature allows solids to pass unhindered with low pressure loss.
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. 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.
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. Rubber material options available include Neoprene, EPDM, Viton, NBR, Natural Rubberfor manyapplications. The TF-1 is ideal for manhole applications, such as junction boxes, diversion chambers and interceptors, where the invert of the pipe is close to the floor of the vault. These vaults are designed to maximise the available gravity head; thus, the invert pipe is as close to the floor as possible. From one-way valves used in automotive fuel pumps to delicate valves used in tubing circuits for heart surgery, for soap dispensers, coffee makers, anti- siphoning valves in shower heads, and toys. 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.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. 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. 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:
