Designed for commercial, mechanical, and industrial piping systems, it opens and closes through a 90-degree rotation, making it straightforward to operate under typical line pressures. The extended neck design accommodates pipe insulation up to 2 inches without interfering with valve operation. Licensed plumbers, pipefitters, and mechanical contractors specify this valve where a reliable, economical shutoff or throttling solution is needed in water service applications.\u003c\/p\u003e\n\u003cp\u003eThis valve is well suited for commercial HVAC hydronic systems, industrial process water lines, and mechanical room piping where lug-style end connections are required for dead-end service capability. The EPDM liner makes it appropriate for most water applications, including chilled water and heating hot water circuits. The gear operator is particularly practical at 20 inches, where direct-lever actuation would require excessive torque. Both commercial and industrial installations benefit from the ductile iron body's durability in demanding service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLug-style body allows dead-end service and independent line section removal\u003c\/li\u003e\n  \u003cli\u003eEPDM cartridge liner recommended for most water service applications\u003c\/li\u003e\n  \u003cli\u003eAluminum bronze disc provides corrosion resistance in water systems\u003c\/li\u003e\n  \u003cli\u003eQuarter-turn (90-degree) operation for fast, positive open and close\u003c\/li\u003e\n  \u003cli\u003eExtended neck accommodates pipe insulation up to 2 inches\u003c\/li\u003e\n  \u003cli\u003eGear operator reduces operating torque on large-diameter valve\u003c\/li\u003e\n  \u003cli\u003eBacked by a 5-year 125% limited warranty from NIBCO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style lug butterfly valve for commercial, mechanical, and industrial piping systems requiring a 20-inch ductile iron valve with EPDM liner and gear operator.

Depressurize and isolate the piping section before installation, and verify flange bolt patterns and pressure ratings are compatible with the mating flanges. The gear operator must remain accessible after installation for periodic exercise and maintenance. Refer to NIBCO technical data sheets and catalogs for engineering details, torque tables, and pressure-temperature ratings before commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Size\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner Material\u003c\/strong\u003e: EPDM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Material\u003c\/strong\u003e: Aluminum Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuation\u003c\/strong\u003e: Gear Operator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Quarter-turn, 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Clearance\u003c\/strong\u003e: Up to 2 inches (extended neck)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5-year 125% limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 039923778000\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: LD-1000-5-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51383934320946,"sku":"LD-1000-5-20","price":9665.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673278.png?v=1782612346","url":"https:\/\/voomisupply.com\/products\/nibco-ld-1000-5-20-lug-butterfly-valve-20-inch-gear-op","provider":"Voomi Supply","version":"1.0","type":"link"}
