By combining the functions of an isolation valve, a silent check valve, and a flow control\/throttling valve into a single unit, this device streamlines your piping installation while reducing overall system footprint and component complexity.\u003c\/p\u003e\u003cp\u003eThe valve operates via a calibrated stem mechanism that allows for precise balancing of system flow rates. The spring-loaded disc design ensures the valve closes promptly upon pump shutdown, effectively preventing backflow and mitigating the risk of water hammer in the hydronic loop.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eIntegrated Flow Control:\u003c\/b\u003e Allows for accurate system balancing to maintain optimal energy efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBackflow Prevention:\u003c\/b\u003e Features a silent, spring-loaded check mechanism that eliminates damaging surges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInstallation Efficiency:\u003c\/b\u003e Reduces the need for multiple separate components, saving space and labor costs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaintenance Isolation:\u003c\/b\u003e Enables reliable shut-off for system servicing without draining the entire loop.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial chilled water and heating water secondary piping, pump discharge stations, and boiler room hydronic circulation systems.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43125813149790,"sku":"132206","price":845.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/132206_image_ccd9587d-287b-453f-92cc-f567970597a7.png?v=1786037973","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-132206-3dv-2nmf-2-npt-triple-duty-valve","provider":"National Boiler Supply","version":"1.0","type":"link"}
