The HG135 is a sleek and compact point of use mixing valve designed to assist in the prevention of scalding. It features a superior, fast acting thermostatic element that provides stable operation at flow rates as low as 0.25 gm (0.95 pm). The Heatguard 135 also reduces the outlet flow to a trickle in the event of a cold water supply failure. The valve inlets and outlet connections are standard 3/8″ supply line compression connections for use with 3/8 in. OD tube. The inlets of the valve feature check valves to prevent cross contamination as well as serviceable strainer screens to prevent the valve from being clogged with dirt or debris. Each valve includes a purpose built mounting bracket and hardware to neatly and securely fasten the valve to the wall. The compact design and pleasant aesthetics allow for this valve to easily be fit under or behind a single basin. Adjustable outlet temperature range: 100°-120°F (38°-49°C).
