The SharkBite Heatguard 160 with Checks is a superior performance Thermostatic Mixing Valve that mixes hot water with cold to deliver tempered water at a constant temperature. The SharkBite Heatguard 160 is intended to supply controlled temperature hot water to any outlet requiring a higher level of protection. The valve is third party listed for individual point-of-use applications. The SharkBite Heatguard 160 features a rapid response thermostatic element for superiorcontrol. The thermostatic element senses the outlet water temperature and reacts to maintain a constant delivery temperature even under changing flows orvariations in supply temperatures or pressures. The valve also reduces the outlet flow to a trickle in the event of a cold water supply failure.
