The CSM-KNOB is a lead-free model, which is what makes it legal for potable water — balancing a DHW recirculation loop means the valve sits in the drinking-water path. Use it to set the return flow on each riser so the far fixtures get hot water without over-pumping the near ones. The standard (non-LF) models in this series are for closed hydronic loops only.\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\u003eBody Material:\u003c\/strong\u003e Lead-Free Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat \/ Seal Material:\u003c\/strong\u003e FKM (Viton)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Hydronic Heating\/Cooling, DHW Recirculation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\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-KNOB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e NSF-61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e Yes\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":31247359770729,"sku":"0856747","price":20.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/71604a0e74755470bb13576a1ed033a7505b8558.jpg?v=1785978253"},{"product_id":"watts-csm-91-3-valve","title":"Watts CSM-91 3 Balancing Valve, Ductile Iron, Grooved","description":"\u003cp\u003eThe Watts CSM-91 3 is a 3\" manual circuit balancing valve with Grooved connections.
