Grohe 34902, Bathtub valve help ID and change part

[Jmclean]

Hello,

I just realized that my bathtub was leaking into the ceiling below. The cartridge of the temperature control mixer seems to be leaking on the outside of the tile, the valve handle that operates the tub faucet seems like it might be leaking into the wall ( the tub drain is not leaking I opened up the wall behind)
Please help identify this valve , thanks in advance
Julian
