Built with a cast iron body, aluminum bronze disc, and stainless steel stem, this valve delivers a strong combination of corrosion resistance and structural durability. A Buna-N seat provides a positive shutoff seal rated for service up to 200 psi and 180 degrees F. The lever handle allows fast quarter-turn operation for isolation or throttling. This valve is installed by licensed plumbers, pipefitters, and HVAC mechanical contractors working on commercial and industrial piping systems.\u003c\/p\u003e\u003cp\u003eThe NLJ140H wafer-style design fits between standard flanges, making it a compact and cost-effective choice for tight mechanical spaces. Its lever handle configuration suits applications where frequent manual operation is required. Typical installations include chilled water, heating hot water, condenser water, and general industrial fluid service lines in commercial buildings and light industrial facilities. The valve is appropriate for both new construction and retrofit piping projects on 4-inch schedule pipe.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron body provides rugged durability for commercial and industrial service\u003c\/li\u003e\n\u003cli\u003eAluminum bronze disc resists corrosion in water and mild fluid applications\u003c\/li\u003e\n\u003cli\u003eStainless steel stem for long service life and resistance to pitting\u003c\/li\u003e\n\u003cli\u003eBuna-N seat rated to 200 psi and 180 degrees F for broad compatibility\u003c\/li\u003e\n\u003cli\u003eWafer design installs between flanges for compact, low-profile mounting\u003c\/li\u003e\n\u003cli\u003eQuarter-turn lever handle enables fast manual isolation or throttling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wafer butterfly valve for 4-inch flanged piping systems conforming to standard flange face dimensions.
