Franke Tap Part Valve SP3308 Hot 133.0150.220 Cold
In recent installation guides this valve 3308R (133.0150.219 Cold /130.0120.220 Hot) is called 3794R (133.0358.053 Hot /133.0358.055 Cold).
It is the same valve.
When your Tap was first produced the manufacturer of your Tap used the SMR valve 3308R. This has 2 flat sides on the nut (SP3308 (aka 3308R). The manufacturer has also used the same valve, albeit with a six sided nut, 3794R. The only difference between these two valves is cosmetic i.e they both have same crucial measurements and are interchangeable i.e you can use a 3308R where you have a 3794R and vice versa. We currently stock both genuine SMR valves and dependent on stock levels, if you order the SMR Mini Valve you might receive either the 3308R or the 3794R. The 3308R currently in stock has a white seal rather than a red or blue (the Hot side has a nick all the way around the nut to distinguish it from the Cold). All valves are labelled by us before shipping. The Hot opens clockwise and the Cold opens anti-clockwise.

Here below is example of the later valve 3794r (SP3794) which is now the replacement for the SP3308(3308R). If your own valve inside your tap has these 6 sides, then the removal tool will NOT be of any use so do NOT buy it.

Recently we have noticed that the new valve is a little stiffer to push the handle onto. We have reported this back to the manufacturer but they assure us that there have been no changes of any consequence and it is just to do with the tolerance on the machining of the valves. If this does occur we would simply recommend ensuring that your own handle is clear inside of any residual debris and that you push the handle on and off the new valve a few times to loosen the splines slightly. You won’t damage your handle.
Tightening your valve: We would also recommend that you do NOT over-tighten this valve. As a rule of thumb, tighten as far as physically possible by hand, and then tighten 1/4 turn with an adjustable spanner.
The Hot and Cold Valve are not interchangeable as one opens clockwise and the other opens anti-clockwise.
