Leonard Valve’s four port point of use valve, Model 170D-LF is available NOW!!! The Model 170D-LF is the newest addition to our POU family and designed with convenience in mind. An 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. ASSE 1070 certified.
