What shower valve is this??

Hoping someone might be able to tell me the make/model of the following shower valve. On top of the value are the numbers 12178 (searched the internet but really didn't find anything that matched this) and the cover states Delta (but also searched their site and didn't see anything that matched) - screws in cover are about at 2 and 7 o'clock. It is a two way valve - e.g., controls both temperature and water flow. Any help would be greatly appreciated. Thank you!

That is a Moen balance pressure faucet. What problems are you having with it? Moen will replace any parts you need free of charge.

Hi John

Thank you for the quick response - no issues with it - having to redo the whole bathroom due to a shower pan leak (in the pad), and was hoping to either just change the cover plate (from chrome to brushed nickel) or if needed replacing it with something else (jury still out) - otherwise it works great - and love the ability to set both pressure and temp.

Thanks again
