Replacement Diaphragm for a BS Series Iris Valve
Although the series BS valve has been obsolete for a number of years, we are still able to offer spare diaphragms and also some that are also common to the BD series valve. Spare diaphragms for the series BS valves are fabricated from sheet material and are available in the following materials:
All diaphragms are supplied complete with stainless steel wires and retaining rivets.
If you are uncertain of the spare diaphragm required for your valve, please let us have the serial No. and we can trace back at least 45 years through our serial No. records. Believe us, there are valves of that age still being used in industry today!!!
