The Model 170D-LF is a four port POU valve designed with convenience in mind, Leonard Valve notes. The installing contractor can feed the faucet fixture with not only tempered water at ideal temperatures for hand wash applications, as well as cold water from the integral "by-pass" feature which is incorporated into the design. 

For those installers who do not want the cold water by-pass, every valve is equipped with a by-pass cap for easy shut off capability. The Model 170D-LF also features a tamper resistant temperature locknut and is ASSE 1070 certified.
