Wafer Concentric Butterfly Valve
Features
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.
