As a critical component of the \u003cstrong\u003ePT-80V\u003c\/strong\u003e series, this tank is engineered to absorb excess water volume as fluid temperatures rise, ensuring that system pressure remains within safe, optimal limits during operation.\u003c\/p\u003e\u003cp\u003eThis vessel utilizes a high-quality diaphragm to create a permanent air cushion, effectively separating the system fluid from the pre-charged air pocket. This design prevents waterlogging, minimizes corrosion, and reduces the risk of relief valve discharge, thereby extending the service life of your circulators and related piping 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 pressure to prevent thermal shock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Prevention:\u003c\/strong\u003e diaphragm design isolates air and water to inhibit internal scaling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Durability:\u003c\/strong\u003e Protects sensitive hydronic components from excessive wear caused by pressure fluctuations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for residential and light commercial hydronic heating systems, radiant floor heating loops, and closed-loop chilled water systems requiring high-efficiency pressure control.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43127839752286,"sku":"1BN323LF","price":745.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/1BN323LF_image_addbb35c-5da6-4d44-abfa-c8aa4ee09f74.jpg?v=1786058099","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-1bn323lf-pt-80v-diaphragm-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
