This component is engineered to facilitate the purging of trapped air from hydronic systems, ensuring optimal thermal transfer and preventing noise or corrosion-related issues within your plumbing and heating infrastructure. The \u003cstrong\u003e113228\u003c\/strong\u003e is designed for high reliability and seamless integration into existing residential or light commercial loop configurations.\u003c\/p\u003e\u003cp\u003eThe valve operates by allowing manual or automatic venting of air pockets that accumulate during system fill or operation. By integrating this purge valve at strategic high points or near the expansion tank, the mechanism effectively purges air without requiring a full system drain-down, significantly reducing maintenance downtime and improving overall circulation efficiency.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimplified Maintenance:\u003c\/strong\u003e Facilitates rapid air venting without extensive system service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Protection:\u003c\/strong\u003e Minimizes oxygen presence to extend the lifespan of system components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Efficiency:\u003c\/strong\u003e Eliminates air-binding to restore full thermal conductivity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for use in hydronic heating systems, primary-secondary loop setups, and domestic water expansion tank maintenance where air control is critical for system health.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43123959300190,"sku":"113228","price":82.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/113228_image_70df1ae4-b1f3-4182-83ff-ae12ffd7a5e2.png?v=1786026361","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-113228-tpv-1-2sm-tank-purge-valve","provider":"National Boiler Supply","version":"1.0","type":"link"}
