LFDDC is a flexible connection equipped with bolted on Tri-Clamp flanges.
The Tri-clamp flange is machined together with a bolt pattern flanges, or is welded together from a bolt pattern flange together with a Tri-clamp flange.
The standard Tri-clamp gasket is replaceable, as well are the gaskets that seal the adapter flange to the flexible connector. For both gaskets there is a choice of a wide range of gasket materials. All the metal parts can be re-used when the flexible sleeve is replaced, this is a great advantage.
The assembly can be done by a wide range of bolts and bolt heads, from various materials, washers can be used, as well as nuts or threaded flanges. Standard is a hexagon head, 2 washers and a nut, for easy disassembly. Other options could be, countersunk bolts, threaded flanges instead of nuts and flanged bolts to replace washers.
By using the standard couplings on the market, you can use a wide variety of connection clamps, such as the standard tri-clamp accessories, or the versions which allow for tool release, or a padlock for instance. Brackets or braces can be placed or can be incorporated in the design to fit magnets, switches, contacts or other electronic devices that either detect the presence of a flexible connection, or keep it in place such as electromagnets can do, even when the clamps are removed. It can also be made suitable for lock out tag out (LOTO). This can all be of importance when the Flexible Connection is close to a rotary valve, screw conveyor, butterfly valve, mill or other mechanical equipment, or when a harmful gas is present inside the tubing.
The LFDDC was initially designed to connect PTFE flexible connections in the most airtight, dust tight, fluid tight manor, and making all the parts re-useable when the flexible sleeve was broken. The design is based on the Flange Fitted principal, and has quick connection type flanges welded or machined together with the flange with bolt pattern. Therefor not only tri-clamp is possible, but almost any type of flange with a quick action coupling.
A flange fitted flexible connection has the best sealing properties and the least amount of crevices or trapped corners or edges, making it the best way to connect a flexible sleeve to a ducting part. By machining a conical edge on the inside the whole LFDDC became free of any unhygienic entrapment or hard to clean places. Making it a hygienic coupling. Because of the rigid metal adapter parts , it becomes vacuum and overpressure resistant at the same time as well as fully customizable to your demands.
There are many application options, including specific options for weighing and dosing techniques, Atex, foodstuffs, chemicals and colour and metal detection.
