This robust flanged valve serves three essential functions in a single body: acting as a shut-off valve, a non-slam check valve, and a flow balancing valve to optimize pump efficiency.\u003c\/p\u003e\u003cp\u003eEngineered for precision control, the internal mechanism utilizes a calibrated position indicator and memory stop to ensure repeatable balancing settings after maintenance. The flow-optimized geometry minimizes pressure drop while preventing backflow and water hammer, ensuring smooth operation in complex hydronic circuits.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Regulation:\u003c\/strong\u003e Precision throttling for accurate system balancing and pump energy optimization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackflow Prevention:\u003c\/strong\u003e Integrated spring-loaded disc design effectively prevents reverse flow and associated mechanical shock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Efficiency:\u003c\/strong\u003e Integrated isolation functionality allows for pump maintenance without the need for additional downstream valves.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Recommended for use in chilled and hot water commercial HVAC loops, primary-secondary pumping systems, and pump discharge header isolation.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43125460303966,"sku":"132122","price":1230.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/132122_image_9301c17a-cb45-4f95-a5f2-b2fcd6cfd863.png?v=1786036217","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-132122-3ds-2-1-2s-flanged-triple-duty-valve-2-1-2","provider":"National Boiler Supply","version":"1.0","type":"link"}
