6.1 Interchangeability of spares
For identification of available spares see pages 24 and 25.
The following Table shows how some parts are interchangeable. For example the line headed main diaphragm
indicates that the diaphragm used in sizes DN15LC, DN15 and DN20 is common to those sizes by the letter
'a'. The letter 'b' indicates that sizes DN25 and DN32 use on common diaphragm.
†
Spare parts for the DP143 and DP163 are different materials and may not be compatible for interchangeability.
