It features a ductile iron body and a epdm seat.\u003c\/p\u003e\u003cp\u003eThis 1 1\/4 inch CSM-82-F static balancing valve is designed for application on medium to high volume flow rate HVAC units. The angled globe design allows for precise control of flow for effective system balancing. The unique cylindrical plug design provides full flow with minimal pressure drops and low operating torque. Ergonomically designed cross handle allows for quick and easy valve setting or shut-off. This valve features durable ductile iron body construction and easily accessible pressure monitoring ports with drip caps to facilitate system balancing and flow measurement. These valves also provide positive shut-off, eliminating the need for a separate service valve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAccurate flow measurement\u003c\/li\u003e\n\u003cli\u003eDurable ductile iron body construction\u003c\/li\u003e\n\u003cli\u003eANSI Class 150 flanged end connections\u003c\/li\u003e\n\u003cli\u003eGlobe style shutoff for reliable isolation\u003c\/li\u003e\n\u003cli\u003eLow torque cylindrical plug design\u003c\/li\u003e\n\u003cli\u003eCross handle shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eDo I need a separate meter to read the flow?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. The CSM-82-F 1 1\/4 is a differential-pressure device: it meters through dual PT (pressure\/temperature) ports with checked drip caps. You connect a balancing meter (or a differential gauge) across the two ports, read the pressure drop, and convert it to GPM using the Watts flow chart for the 1-1\/4\" body. The valve does not display flow on its own. If you want set-and-read balancing without a meter, use the Watts iDROSET CSD direct-reading series instead.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan it also shut off the circuit?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. The CSM-82-F 1 1\/4 gives positive, drip-tight shutoff, so it doubles as the service valve for the circuit and you do not have to buy and install a separate ball valve next to it. The memory stop preserves your balanced setting: close the valve for service, reopen it against the stop, and the circuit returns to the same flow without rebalancing.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I use it on a domestic hot water recirculation line?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo. The CSM-82-F 1 1\/4 is not a lead-free model, so it is restricted to closed hydronic heating and chilled-water loops and other non-potable service. For DHW recirculation balancing, choose the lead-free equivalent — the Watts LFCSM-61-S (PT-port) or LFiDROSET CSD (direct-reading).\u003c\/dd\u003e\n\u003c\/dl\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Balancing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Flanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat \/ Seal Material:\u003c\/strong\u003e EPDM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class:\u003c\/strong\u003e Class 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Hydronic Heating\/Cooling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 Year Limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e CSM-82-F 1 1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASSE-6510, ASSE-536\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalancing Type:\u003c\/strong\u003e Manual Circuit Balancing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Functions:\u003c\/strong\u003e Balancing;Flow Measurement;Shutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Readout:\u003c\/strong\u003e Dual PT ports, 1\/4\" SAE 45° flare, checked w\/ drip caps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory Stop:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive Shutoff:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":54934652223787,"sku":"1000001114","price":978.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/57c0bb997b51efade6e895206d13b07876aa5c1b_49dbb108-be88-4a13-b60b-7ed1b662a2bd.jpg?v=1785978130","url":"https:\/\/citysupplygroup.com\/products\/watts-1000001114","provider":"City Supply","version":"1.0","type":"link"}
