Master tempering valve series
www.watts.com
Series N170-M3, the next generation of master tempering valves for hot water distribution in commercial and institutional facilities, includes five valves (3/4", 1", 11/4", 11/2" and 2"), and is listed to ASSE 1017 and replaces the current Series N170-M2. Complies with CSA B125.3 through iapmo and carries the cupc seal. Although the N170-M3 has been re-engineered, it maintains the exact roughing-in dimensions of its Series M2 predecessor for trouble-free direct replacement. Watts.
