Built with a brass body and brass\/PTFE trim with EPDM\/PTFE sealing components, this valve handles working pressures up to 200 psi and temperatures up to 250 degrees F. The press-end connection style allows for fast, flameless installation in 1-inch nominal copper piping. Domestically manufactured, this valve is sized for residential and light commercial hydronic heating and cooling applications where repeatable, reliable flow adjustment is essential.\u003c\/p\u003e\u003cp\u003eThis valve is installed in closed hydronic circuits — including chilled water, hot water heating, and fan coil supply or return lines — where balancing individual circuit flow is necessary to maintain system efficiency. With an inlet-to-outlet length of 6.77 inches and a top-to-inlet center dimension of 4.06 inches, it fits into standard mechanical room piping layouts. It is intended for installation by licensed plumbers or mechanical contractors working on hydronic systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eManual flow control with press-end connections for flameless installation on 1-inch copper pipe\u003c\/li\u003e\n\u003cli\u003eBrass body construction rated for 200 psi working pressure\u003c\/li\u003e\n\u003cli\u003eTemperature rated to 250 degrees F for hot water and chilled water service\u003c\/li\u003e\n\u003cli\u003eBrass\/PTFE trim with EPDM\/PTFE seals for long-term sealing reliability\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured to support Buy American and project specification requirements\u003c\/li\u003e\n\u003cli\u003e5-year limited warranty from NIBCO\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation circuit balancing valve for 1-inch press-end copper hydronic piping systems.

Depressurize and drain the affected circuit before removing or installing any valve. Press-end fittings require the appropriate press tool and jaw set rated for the connection size and valve body material. Follow all applicable local plumbing codes and ASME\/ANSI standards for hydronic system service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Press\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet to Outlet Length\u003c\/strong\u003e: 6.77 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop to Inlet Center\u003c\/strong\u003e: 4.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Brass\/PTFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: EPDM\/PTFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: PC-1810-LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 years Limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3992338450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51671625171250,"sku":"3992338450","price":138.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bdc244e837f52166cc56df4a39a449b.jpg?v=1787961167","url":"https:\/\/voomisupply.com\/products\/nibco-3992338450-circuit-balancing-valve-1-inch-press","provider":"Voomi Supply","version":"1.0","type":"link"}
