As part of Armstrong's CBV family, it uses the ARMflo venturi-style, globe-pattern design to reduce turbulence and preserve a stable differential-pressure signal for accurate balancing. The ½\"–2\" CBV range features multi-turn adjustment with hidden memory stops to lock in the balance point, enabling repeatable settings during commissioning and service. The valve enables precision flow measurement, pump throttling and, when paired with compatible instrumentation, temperature monitoring to verify system performance. Common applications include commercial HVAC distribution networks and other hydronic systems where test-and-balance technicians require reliable flow control across multiple circuits. The 2\" NPT threaded configuration provides robust, straightforward installation for mid-to-large diameter piping, helping ensure consistent circuit balance and predictable energy use in the installed system.\u003c\/p\u003e\u003c\/div\u003e","brand":"Armstrong","offers":[{"title":"New","offer_id":51660113871150,"sku":null,"price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_03a0a770-55eb-4808-ab95-d14757f6186a.jpg?v=1769533134","url":"https:\/\/plgautomation.com\/products\/armstrong-international-cbv-1-1-2-circuit-balancing-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
