Cast from resilient, commercial-grade bronze, these components combine an isolation shut-off valve and an auxiliary tank drainage port within a single high-durability body assembly. Engineered explicitly to maintain a strict volumetric atmospheric cushion inside conventional steel compression reservoirs, they prevent system water from completely water-logging the tank shell, ensuring continuous system safety against thermal water expansion spikes.\n  \u003c\/p\u003e\n\n  \u003cp style=\"margin-bottom: 12px;\"\u003e\u003cstrong style=\"font-size: 15px; color: #111;\"\u003eAdvanced Engineering \u0026amp; Architectural Advantages:\u003c\/strong\u003e\u003c\/p\u003e\n  \n  \u003cul style=\"margin-top: 0; margin-bottom: 20px; padding-left: 20px;\"\u003e\n    \u003cli style=\"margin-bottom: 10px;\"\u003e\n      \u003cstrong\u003eConsolidated All-in-One Architecture:\u003c\/strong\u003e Combines a primary system line shut-off configuration and a high-flow drain valve into a unified bronze footprint, significantly reducing physical leak paths and mechanical field assembly labor times.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 10px;\"\u003e\n      \u003cstrong\u003eSmart Gravity Flow Restriction:\u003c\/strong\u003e Built with internal baffling that slows downstream thermal gravity circulation currents between the boiler main and the compression cell, holding tank temperatures low to prevent air bubbles from dissolving back into system fluid.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 10px;\"\u003e\n      \u003cstrong\u003eFlexible Air Venting Core:\u003c\/strong\u003e Outfitted with dual rigid copper air tube extensions that capture entrained micro-bubbles and route them cleanly into the expansion core to sustain the pressure blanket.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp style=\"margin-top: 16px; margin-bottom: 0;\"\u003e\n    \u003cstrong\u003eSystem Application Envelope:\u003c\/strong\u003e Universally certified for closed hydronic heating loops, water\/glycol solutions up to 50% concentration, solar thermal setups, and closed commercial cooling applications.\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":42910021648478,"sku":"TACO-TANK-DRA","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Studio_front_product_shot_showcasing_a_Taco_bronze_hydronic_combination_expansion_tank_drain_fitting_next_to_its_included_dual_copper_air_tube_extension_rods_isolated_cleanly_on_a_solid_white_background..jpg?v=1782131545","url":"https:\/\/nationalboilersupply.com\/products\/taco-tank-drains-fittings","provider":"National Boiler Supply","version":"1.0","type":"link"}
