The body and disc are both ductile iron, with a stainless steel stem and a Buna-N seat for reliable shutoff and flow isolation. The lever handle allows direct manual operation without a gear actuator, making it well suited for accessible installations where quick open-close control is needed. This valve meets MSS SP-67 and carries U.S. Coast Guard Category A approval, along with MSS SP-25 marking standards. Licensed plumbers and pipefitters are the primary installers, typically in commercial HVAC, industrial fluid systems, and marine applications.\u003c\/p\u003e\u003cp\u003eThe NLH250K is built for 6-inch wafer-style installation between standard ANSI flanges in piping systems carrying water or compatible fluids at up to 250 psi and up to 180 degrees F. The lever handle configuration suits locations where the valve is easily reachable and operated by hand. Typical install scenarios include chilled water loops, condenser water lines, fire protection branch lines, and general service piping in commercial buildings and marine vessels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250 psi maximum working pressure for demanding fluid service applications\u003c\/li\u003e\n\u003cli\u003eDuctile iron body and disc provide strength and corrosion resistance in commercial piping\u003c\/li\u003e\n\u003cli\u003eStainless steel stem (Grade 416) resists corrosion and wear over repeated cycles\u003c\/li\u003e\n\u003cli\u003eBuna-N seat material compatible with water and a wide range of general-service fluids\u003c\/li\u003e\n\u003cli\u003eLever handle enables direct manual operation without a separate actuator or gear operator\u003c\/li\u003e\n\u003cli\u003eLead-free construction suitable for potable and regulated fluid systems\u003c\/li\u003e\n\u003cli\u003eMeets MSS SP-67, MSS SP-25 marking standards, and U.S. Coast Guard Category A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wafer butterfly valve for installation between standard ANSI flanges on 6-inch pipe in commercial HVAC, industrial, and marine fluid piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local mechanical codes. Depressurize and isolate the line completely before removing any existing valve or installing this unit. Wafer valves require proper flange alignment and appropriate hardware to prevent leakage at the seat. Confirm fluid and temperature compatibility with the Buna-N seat before placing the valve in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel, Grade 416\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Wafer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 14.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: MSS SP-67, MSS SP-25, U.S. Coast Guard Category A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.23 pounds\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: NLH250K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51539274793266,"sku":"NLH250K","price":617.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffe9899cc80d1f9651eab72fe13cfc28_41f51b3b-a937-44cb-ac0c-65eb966a3061.jpg?v=1785837568","url":"https:\/\/voomisupply.com\/products\/nibco-nlh250k-wafer-butterfly-valve-6-inch-250-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
