The valve features a ductile iron body rated at 125\/150 lb pressure class, an aluminum bronze disc, and a stainless steel stem with stainless steel taper pin for corrosion resistance and long service life. An EPDM seat provides a tight seal against water media. A gear actuator is included for controlled, low-effort operation on this large-diameter valve. This is a domestically produced valve suitable for commercial and industrial piping systems where dependable isolation is required.\u003c\/p\u003e\n\u003cp\u003eThe LD-1000-5 series lug butterfly valve is suited for 20-inch piping in HVAC heating and cooling distribution systems, as well as hot and cold potable water supply lines. The lug-style body allows the valve to be installed as a dead-end shutoff, enabling one side of the line to be removed without disturbing the opposite flange connection. Licensed plumbers, pipefitters, and mechanical contractors typically handle installation in commercial and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLug-style body allows dead-end service without full line shutdown\u003c\/li\u003e\n  \u003cli\u003eDuctile iron body rated at 125\/150 lb pressure class for robust service\u003c\/li\u003e\n  \u003cli\u003eAluminum bronze disc for corrosion resistance in water service\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem and stainless steel taper pin for durability and reliability\u003c\/li\u003e\n  \u003cli\u003eEPDM seat compatible with water media including potable applications\u003c\/li\u003e\n  \u003cli\u003eGear actuator provides controlled operation on large 20-inch diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in HVAC systems and hot and cold potable water piping.

Isolate and depressurize the line completely before removing or installing the valve. Confirm flange bolt pattern and gasket compatibility with the mating flanges prior to installation. Verify gear actuator travel stops are set correctly after installation and before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LD-1000-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 20 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\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\u003eSeat Material\u003c\/strong\u003e: EPDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Pin Material\u003c\/strong\u003e: Stainless Steel (Taper Pin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Gear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia\u003c\/strong\u003e: Water (HVAC, Hot and Cold Potable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 39923778000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51673094357298,"sku":"39923778000","price":8369.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7e566455e1618f592538e8682550a6d.jpg?v=1787977257","url":"https:\/\/voomisupply.com\/products\/nibco-39923778000-lug-butterfly-valve-20-inch-gear","provider":"Voomi Supply","version":"1.0","type":"link"}
