Lug Concentric Butterfly Valve
Features
1.Small in size and light in weight, easy to install.
It can be mounted wherever needed,Suitable for various actuators.
2.Lug Concentric butterfly valve can be used on the end of the pipeline .
3.Lug Concentric butterfly valve has threaded metal inserts (usually stainless steel)installed in the valve’s bolt holes .
4.The inserts are threaded on the both ends,which allows this lug style valve to be installed into a system using two sets of bolts and no nuts for each hole.
5.The valve is installed between flanges using a separate set of bolts for each side of the flange.
6.This setup permits either side of the piping system to be disconnected without disturbing the other side.
When used in the end of pipeline service,It has a reduced pressure rating ,E.g,it rates 150PSI when mounted between two flanges,while it rates just 75 PSI when mounted in the end of pipeline servic
Advantage
The concentric type is a standard and general use butterfly valves.
The shaft is located in the centre of the disc and pipeline.
The disc outer diameter is bigger than the inner diameter of the valve seat.
This arrangement creates an interference fit whereby part of the disc is in contact or rubs the seat during the opening or closing of the valve. As a result, a bubble-tight shut off is achieved.
The disc is made of metal whereas the seat is a softer material (NBR, EPDM, PTFE, VITON). Soft seat butterfly valves are suitable for low pressure and non-critical applications up to Class 150/PN16.
