The Heatguard® 110-D is a Temperature Actuated Mixing Valve that mixes hot water with cold to deliver tempered water at a controlled temperature to 120°F (49°C) maximum and is designed to assist in the prevention of scalding.

The Heatguard® 110-D is intended for installation at the water heater to distribute controlled temperature water through a domestic hot water system.

The SharkBite® Heatguard® 110-D incorporates a fast acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. The valve also greatly reduces the outlet flow in the event of a cold water supply failure.

  • Delivers water at a maximum of 120°F (49°C) throughout the system:
    Safer hot water from all outlets.
  • Allows the heater to be set at 140°F (60°C) or higher:
    Greater effective hot water volume yields less chance of Legionella bacteria within the cylinder.
  • Every valve is tested for performance prior to shipping:
    Specify and install with confidence!
  • Robust, low complexity construction:
    Superior reliability, improved user safety.
  • Unique, purpose designed adjuster tool (included with each valve):
    Minimizes unauthorized tampering with valve setting.
  • Listed by IAPMO and ASSE:
    Inspector friendly, peace of mind!
