Description:

Watts Series N170 hot water master tempering valves are especially designed for use on larger hot water supply systems for mixing hot and cold water for a variety of applications to extend the hot water supply. This series uses paraffin-based thermostat to sense and adjust outlet temperature.






Features:

  • 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

Specifications:

Maximum Operating Pressure 125psig (861 kPa)
Maximum Hot Water Temperature 200°F (93°C)
Minimum Hot Water Supply Temperature 5°F (3°C) Above Set Point*
Temperature Adjustment Range** 90 - 180°F (32 - 82°C)
Hot Water Inlet Temperature Range 120 - 180°F (42 - 82°C)
Cold Water Inlet Temperature Range 40 - 80°F (4 - 27°C)
Listing ASSE 1017, IAPMO CUPC
Approval Standards ASSE 1017, CSA B125.3

* With Equal Pressure
** Low Limit cannot be less than the cold water temperature. For best operation, hot water should be at least 5°F (3°C) above desired set point.
