The Chateau Posi-Temp Single Handle Shower Valve is an important part of creating your ideal 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 slip fit CC connections are part of the quality design you can expect from Moen.
