The \u003cstrong\u003e110198LF\u003c\/strong\u003e model incorporates a fast‑fill feature that quickly restores system pressure after purging or maintenance.\u003c\/p\u003e\u003cp\u003eThe valve combines a three‑way throttling function with an integrated fast‑fill pilot, allowing pressure to be built up through a dedicated fill port while the main valve remains sealed. This dual‑action design minimizes water hammer and shortens start‑up times, delivering consistent flow rates and protecting equipment downstream.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Fill Capability:\u003c\/strong\u003e Restores pressure up to 150 psi within seconds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree‑Way Control:\u003c\/strong\u003e Provides precise modulation for heating and cooling circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Water Hammer:\u003c\/strong\u003e Integrated pilot design mitigates pressure spikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Cast‑iron body resists corrosion in aggressive water chemistries.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial HVAC chillers, boiler feedwater systems, and large‑capacity hydronic heating loops where rapid system recovery and precise flow control are critical.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43123842252894,"sku":"110198LF","price":252.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/110198LF_image_8ad72a6f-ce39-4b25-90d0-315e124720e6.png?v=1786019968","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-110198lf-dual-unit-valve-with-fast-fill","provider":"National Boiler Supply","version":"1.0","type":"link"}
