The \u003cstrong\u003eArmstrong 572018-010\u003c\/strong\u003e, identified as model \u003cstrong\u003eSX-160V\u003c\/strong\u003e, provides a reliable solution for storing excess fluid volume to maintain optimal system charge pressure and prevent premature relief valve discharge.\u003c\/p\u003e\u003cp\u003eThis diaphragm expansion tank utilizes a flexible membrane to separate the system water from the air cushion. As temperatures rise and fluid expands, the diaphragm flexes to absorb the volume increase, effectively buffering the system and preventing unnecessary water make-up, which helps to extend the lifespan of your boiler and pump components.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Maintains stable system charge pressure by buffering fluid expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e Prevents nuisance relief valve activation to minimize heat loss and water waste.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Longevity:\u003c\/strong\u003e Reduces mechanical stress on hydronic components and system piping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Design:\u003c\/strong\u003e Engineered for space-efficient integration into residential and commercial hydronic setups.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for closed-loop hydronic heating systems, radiant floor installations, and boiler-fed space heating circuits requiring consistent pressure control.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133390127198,"sku":"572018-010","price":2142.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/572018_010_image_67695066-5e35-4b49-bd5f-b765ca0e7053.png?v=1786105098","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-572018-010-sx-160v-diaphragm-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
