1 Datasheet ERHARD ECLI butterfly valve
2 Two types of valves are mainly used for shutting off pipelines in sewage engineering or industrial applications: One of these is the gate valve, which was developed in the ancient world and is still used in many applications today thanks to its sophisticated technology and, above all, the free passage it provides when in the open position. The other is the butterfly valve, where a sturdy valve disc is moved between the open and closed position in the media flow, and which has a much smaller design height than a gate valve. Where high pressures and large nominal sizes are involved, double-eccentric butterfly valves such as the ERHARD ROCO Premium butterfly valve are mainly used, since their design guarantees safe opening and closing even under extreme conditions as well as reliable cavitation protection. Quite often, however, the demands made on shut-off valves are simple e. g. where only small pressures or sizes are required or if the valve is only rarely used, such as is the case with servicing valves up- or downstream from control valves. The is the perfect solution here, since it combines the small design height of a butterfly valve with the cost advantages of a gate valve all in a shorter face-to-face dimension. The can be used for applications including cold water and drinking water as well as general industrial applications. Thanks to numerous material options for the valve disc and seal, special application cases can also be realised without any problems. They are available in nominal sizes of DN 32 to DN 300 in numerous versions and can be combined with numerous drive options. 2

14 Notes on installation and mounting The following points must be heeded when mounting ERHARD ECLI butterfly valves in pipes: The distance between the flanges must be large enough for the butterfly valve to be pushed in without displacing the seals [1] or having longitudinal forces acting on them. The valve disc must be in the slightly open position shown in the drawing. The butterfly valve must not be either closed or fully open during mounting. The flanges must be mutually parallel in order to guarantee perfect contact with the butterfly valve after tightening. When the butterfly valve is already mounted, the flanges must not be welded with the pipe since the heat produced by the welding process can damage the seals. The butterfly valve is opened completely before the flange screw attachment is tightened [2] in order to guarantee trouble-free operation. s can be installed in both vertical and horizontal pipes and are fully functional independently of the direction of flow. For sizes larger than DN 300 we recommend a horizontal position for the drive shaft. 1 2 Used as an end valve, consider the following operating pressure size DN Max. allowed operating pressue, used as end valve, in bar Wafer type Lug type
