The Model 170D-LF is a four-port POU valve designed with convenience in mind, the company says. Contractors can feed the faucet fixture with tempered water at ideal temperatures for handwashing 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. WWW.LEONARDVALVE.COM
