Sized for 3-inch pipe, it features a ductile iron body, stainless steel disc, and stainless steel stem paired with a Buna-N seat. The lever handle allows for quick quarter-turn operation without the need for a gear actuator. This valve is typically installed by licensed plumbers, pipefitters, or mechanical contractors working on commercial or industrial piping systems. At 11.68 pounds, it is built for durability in demanding service environments.\u003c\/p\u003e\u003cp\u003eThe NLG350F is suited for use in water supply, HVAC hydronic systems, and general-purpose fluid handling applications where a lug-type butterfly valve is specified. The lug design allows the valve to be used as a dead-end service valve, meaning one side of the piping system can be disconnected without draining the entire line. This makes it a practical choice for maintenance-heavy systems requiring periodic isolation of individual sections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLug-style body enables dead-end service without full system shutdown\u003c\/li\u003e\n\u003cli\u003eDuctile iron body provides strength and impact resistance for industrial use\u003c\/li\u003e\n\u003cli\u003eStainless steel disc and stem resist corrosion in fluid handling applications\u003c\/li\u003e\n\u003cli\u003eBuna-N seat material offers reliable sealing against water and general-purpose fluids\u003c\/li\u003e\n\u003cli\u003eLever handle delivers fast quarter-turn open and close operation\u003c\/li\u003e\n\u003cli\u003e3-inch pipe size fits standard commercial and industrial piping configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation lug butterfly valve for 3-inch pipe systems in commercial HVAC, plumbing, and general fluid handling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the system before installing or replacing the valve. Verify flange bolt pattern and pressure rating compatibility with the existing piping system before installation.
