As a result of exhaustive testing it has been decided to change the supplier of over-centre valves and check valve cartridges mounted to the cylinders of MK6, SB30 and SB33 units.
Existing stocks of SUN cartridges will be phased out and our new supplier's valves mounted.
The cavity of our new supplier's cartridge is different to the "SUN" cartridge. This means that should you wish to upgrade any machines, the cartridge block must also be changed.
All MK6, SB30 and SB33 Sidelifters from Serial Number 6301 on will have the new cartridge valves fitted, as does serial number 6254.
