Utilizing advanced thermal actuation technology, it maintains a stable outlet temperature while compensating for changes in inlet pressure and temperature. Commonly installed near boilers, water heaters, and central hot water plants, it is used in hospitals, schools, hotels, apartment buildings, and other facilities requiring centralized temperature control. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"665\" data-end=\"682\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"683\" data-end=\"1270\"\u003eThe MM431-1 is widely used in domestic hot water systems, commercial plumbing installations, institutional buildings, healthcare facilities, hospitality venues, educational campuses, and industrial process water systems. Installed at the hot water source, it provides tempered water for distribution throughout the building while reducing the risk of scalding and improving energy efficiency. The valve is designed for master mixing applications and should be used in conjunction with point-of-use temperature control devices where required by code. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1272\" data-end=\"1301\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1302\" data-end=\"2180\"\u003e• Manufacturer Part Number (MPN): MM431-1\u003cbr data-start=\"1343\" data-end=\"1346\"\u003e• Brand: Watts Powers\u003cbr data-start=\"1367\" data-end=\"1370\"\u003e• Product Type: Master Thermostatic Mixing Valve\u003cbr data-start=\"1418\" data-end=\"1421\"\u003e• Series: 431 \/ MM430 Series\u003cbr data-start=\"1449\" data-end=\"1452\"\u003e• Nominal Valve Size: 3\/4 in.\u003cbr data-start=\"1481\" data-end=\"1484\"\u003e• Inlet Connection: 3\/4 in.
