The Caleffi MixCal 521 series comprises three-way thermostatic mixing valves designed for use in hot water or radiant heating systems. These valves combine incoming hot and cold water to produce an output of water at the desired constant set temperature. They also protect against pressure fluctuations.<\/p>","notice":null,"product_id":473057,"model_number":"521516A","permission_tags":[],"image":{"src":"\/imager\/generalimages\/products\/2709772\/Caleffi-521616A_9d774b89831857b4dfc965837c0ae6fd.webp","srcset":"\/imager\/generalimages\/products\/2709772\/Caleffi-521616A_9d774b89831857b4dfc965837c0ae6fd.webp 300w","alt":"CALEFFI 521516A 3\/4\" PRESS MIXCAL\n3-WAY THERMOSTATIC MIXING VALVE W\/\nTEMP GAUGE"},"substitutes":null,"uoms":[{"label":"ea (1)","value":{"um":"ea","qty":1,"increment":1}}],"nonstock":false},"substitutes":[],"images":[{"url":"\/imager\/generalimages\/products\/2709772\/Caleffi-521616A_5472332afa344033d2bf9e7b6b9d883e.webp","alt":"CALEFFI 521516A 3\/4\" PRESS MIXCAL\n3-WAY THERMOSTATIC MIXING VALVE W\/\nTEMP GAUGE"}],"productData":null,"branches":[{"title":"Coldwater","warehouseId":11},{"title":"Elkhart","warehouseId":1},{"title":"Jenison","warehouseId":6},{"title":"Michigan City","warehouseId":4},{"title":"Plymouth","warehouseId":2},{"title":"South Bend","warehouseId":3},{"title":"Springfield","warehouseId":8},{"title":"Sturgis","warehouseId":12},{"title":"Warsaw","warehouseId":7}]}
