Rated for 125\/150 lb service and up to 180 degrees F, it handles air, oil, and water applications including compressed air and vacuum lines. The valve features a ductile iron body, aluminum bronze disc, and 416 stainless steel stem pin, paired with a Buna-N seat and a manual gear operator for precise, low-effort actuation on larger-diameter lines. It is domestically manufactured and carries a 5-year limited warranty.\u003c\/p\u003e\u003cp\u003eThis valve is suited for commercial HVAC, plumbing, and light industrial process piping where a lug-style configuration is required. The lug pattern allows the valve to be installed as an end-of-line or dead-end service valve without requiring a downstream flange. It is commonly specified on chilled water, condenser water, compressed air, and general water distribution systems at the 4-inch pipe size. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLug-style body allows end-of-line installation without downstream flange\u003c\/li\u003e\n\u003cli\u003eDuctile iron body rated for 125\/150 lb flanged service\u003c\/li\u003e\n\u003cli\u003eAluminum bronze disc resists corrosion in water and oil media\u003c\/li\u003e\n\u003cli\u003e416 stainless steel stem pin for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBuna-N seat compatible with air, oil, and water service\u003c\/li\u003e\n\u003cli\u003eManual gear operator provides controlled actuation on 4-inch diameter valve\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured with 5-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4-inch ANSI Class 125\/150 lb flanged piping systems in commercial and light industrial applications handling air, oil, or water media, including compressed air and vacuum services.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the piping section completely before removing any existing valve or fitting. Lug-style valves require proper bolt torque applied evenly across all flange lugs — refer to the manufacturer installation sheet for the torque sequence appropriate to the gasket and flange material in use. Verify media compatibility with Buna-N seating before commissioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LD-2100-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 125\/150 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Air, Oil, Water (including compressed air and vacuum)\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: Aluminum Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Pin Material\u003c\/strong\u003e: 416 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Manual Gear Operator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Lug Style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 Years Limited\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: NLG160H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51620785619250,"sku":"39923720788","price":597.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8f6a1c51f3695f7465404f815c61c9e.jpg?v=1787346374","url":"https:\/\/voomisupply.com\/products\/nibco-nlg160h-lug-style-butterfly-valve-4-inch-125-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
