San Marco Quinter Tap Valve

The 3794R Tap Valve  is a quarter turn Tap Valve (Hot or Cold). See below for more information on product codes and measurements.

Please Note: This Valve can also be called SP3794 or 3308R or 133.0150.219 Cold /130.0120.220 Hot (Depending on the age of your Taps and Installation Guide) It is the same valve.

The Hot and Cold Valve are not interchangeable as one opens clockwise and the other opens anti-clockwise.

This post covers both types of mini valves that were (and are) used in the production of your Tap. and gives advice regarding tools to extract your valve. We currently stock both genuine San Marco / SMR valves .The Hot opens clockwise and the Cold opens anti-clockwise.

Do you need a special tool to remove your Valve ? : Check which Valve is in your own tap before removing in case you have the earlier 3308R version in your Tap. Its all covered, including pictures of both Valves, in our Guide here: Changing the SMR Mini Valve.which includes advice on how to remove either valve. No Brass Bush is required with this Tap Valve.   Here below is the 4013R Removal Tool Product if you have the earlier 3308R (SP3308) and want to order it. The 4013R Tool does NOT fit the 3794R (SP3794) with the six sided nut.  

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 just ensure 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.
