Valve 1 1/4" - Model 1510

Valve installed to toilets at Hallberg-Rassy since 2017.
Combine with handle 40-500115. 

Note that if you like to upgrade to these valves from the old valves used before 2017 you will need some fittings to be able to fit the handle in the holes through the toilet wall.
The reson is that the newer valve is shorter than the old version.
