Cash Acme, 24509, HG110-D 3/4' 230 PSI Lead Free Thermostatic Mixing Valve with CPVC ConnectionsThe 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. The Heatguard® 110-D 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 the domestic hot water system or at point-of-use applications. The valve delivers water at a maximum of 120°F (49°C), allowing the heater to be set at 140°F (60°C) or higher, thus providing a greater effective volume of hot water and reducing the chances of Legionella bacteria growth in the water.The 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.The Heatguard® 110-D features a locking mechanism to prevent unwanted adjustment above 120°F (49°C).Features:Certified for distribution and point-of-use applications. Safer hot water from all outlets.Allows the water heater to be set at 140°F (60°C) or higher: Greater effective hot water volume yields less chance of Legionella 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.Adjustable and lockable mechanism: Minimizes unauthorized tampering with valve setting Factory set, locked to maximum 120°F (49°C)Listed by IAPMO, CSA, and ASSE: Inspector friendly, peace of mind!Application:Domestic and Commercial hot water distribution. To control water temperature at the source of heat (hot water tank), point-of-use (sinks, lavatories, or bath tubs) or multiple fixtures (multiple sinks or gang shower applications where bather has no access to temperature control).
