Description
The N170 Master Tempering Valve Series is designed for use in commercial and institutional applications, to mix hot and cold water to reduce high service water temperature to the building distribution piping system. The N170 series is designed for installation at the hot water source. Rough-in dimensions are identical to earlier N170 models making replacement fast and easy. The N170 features bronze body construction, a copper/paraffin thermostat assembly and a lockable temperature adjustment for increased safety. Polysulfone internals resist excessive heat, liming and corrosion, and a single-seat design ensures tight shut-off in the event of cold water supply loss. The N170 is listed to ASSE 1017 and IAPMO cUPC in compliance with CSA B125.3.

Features:
  • Solid bronze construction provides years of dependable service
  • Multi-directional mounting
  • ASSE 1017 and IAPMO CUPC Listed
  • N170-M3 uses paraffin-based thermostat to sense and adjust outlet temperature
  • Dirt and lime resistant poppet and seat design
  • Virtual shutoff if supply pressure fails
  • Vandal-resistant locking mechanism to secure temperature setting
  • Factory tested

Watts Has Improved the N170's All Around Performance...
  • ASSE 1017 listing and CSA B125.3 compliance ensure safe, consistent performance over time.
  • Broader temperature range eliminates the need for low temperature models. The M3 model operates safely over a range of 90-180°F (32°-82°C)
  • Vastly improved low flow control (as low as 3.0 gpm, 11 lpm) for applications where minimum flow performance is critical
  • Approach temperature (hot water inlet - mixed outlet) of 5°F (3°C) provides maximum mixed outlet temperature for installations where hot water is generated at lower temperatures
  • Now offered with checkstops and integrated filters for new installations as well as without for retrofit installations.
