The Chateau Posi-Temp Single Handle Tub and Shower Valve is an important part of creating your ideal bath and shower unit. Pressure balancing technology maintains the selected discharge temperature to within 3 degrees Fahrenheit. You'll never experience an irritating hot or cold surge in water temperature - or the shock associated with it. Even a dishwasher running or a toilet flushing won't disrupt the comfort of your shower. An adjustable temperature limit allows you to set the maximum water temperature for added safety. Solid, attractive metal construction and 1/2'' slip fit CC connections are part of the quality design you can expect from Moen.
