Correct balancing of hydraulic circuits ensures optimum energy distribution, resulting in more efficient and economical  operation in accordance with energy savings guidelines.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eWith an inline balancing flow meter, any qualified installer can set the appropriate flow for the system without costly measuring devices. The flow measurement is based on the principle of a baffle float. The flowmeter is built into the housing. The balancing can be carried out with a screwdriver at the adjusting screw. The reading position is the bottom line of the baffle float. The valve can be installed in a horizontal, vertical or inclined position. Care should be taken in order to ensure that the arrow is pointing in the direction of the flow.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003ch3\u003eMaterials\u003c\/h3\u003e\n\u003cp\u003eValve Body: brass\u003cbr\u003eSight glass: high-performance composite\u003cbr\u003eBaffle float: high-performance composite\u003cbr\u003eSpring: stainless steel\u003cbr\u003eSeals: EPDM\u003cbr\u003eStem guide bearing: PTFE\u003c\/p\u003e\n\u003ch3\u003e\n\u003cbr\u003ePerformance\u003c\/h3\u003e\n\u003cp\u003eSuitable Fluids: water, glycol solutions\u003cbr\u003eMax. percentage of glycol: 50%\u003cbr\u003eMax. working pressure: 150 psi (10 bar)\u003cbr\u003eWorking temperature range: 32 - 250°F (0–120°C)\u003cbr\u003eFlow range: 2 - 8 gpm (8 -30 lpm)\u003cbr\u003eFlow coefficient, fully open: Cv 5.8 (Kvs 5.0)\u003cbr\u003eMeasuring accuracy: ±10%\u003cbr\u003eConnections: 1\" union thread\u003c\/p\u003e","brand":"Hydro Solar Solutions","offers":[{"title":"Default Title","offer_id":33827595223178,"sku":"NA223529","price":99.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/products\/inline-balancing-flow-meter-caleffi-na223-series-1-bspt-threaded-16355992273034.png?v=1588627724","url":"https:\/\/hydrosolar.ca\/en-us\/products\/inline-balancing-flow-meter-caleffi-na223-series-1-bspt-threaded","provider":"Hydro Solar Innovative Energy","version":"1.0","type":"link"}
