Product Detail
Anatomy of a Valve
Every shower has a valve that acts like an engine — shifting flow, regulating temperature and driving performance — and there are many options of design, functionality and operation suited to different applications.
The valve is placed behind the wall and connects directly to the hot and cold water lines to regulate flow and temperature. Most valves are available in a variety of connection types. A cartridge inserted into the valve connects to the external trim handles to control the mixture of hot and cold water and flow through the faucet based on the handle position.
With any Moen valve, you can be certain of unsurpassed safety, comfort and reliability since our valves meet applicable pressure-balancing or thermostatic safety codes and eliminate worry about hot or cold water surges. Plus, you can rely on our quality construction and dependable operation since each valve is backed by our Limited Lifetime Warranty.
