Nibco nlb95txc 1-1/2 in Threaded Full Port Ball Valve 600 Psi

Product Description

The NIBCO nlb95txc is a two-piece, full-port bronze ball valve designed for quarter-turn shutoff in commercial, residential, mechanical, and industrial piping systems. It features female NPT threaded ends on both sides for straightforward installation into existing threaded pipe runs. The ball and stem are stainless steel and silicon bronze respectively, providing corrosion resistance across a wide range of fluid applications. Rated at 600 PSI cold working pressure, this valve handles demanding service conditions. The NIBSEAL extended insulated handle is a standout feature, offering a secure, comfortable grip for operators working in tight or insulated installations. Licensed plumbers and mechanical contractors are the primary installers of this valve.

This valve is suited for 1-1/2 inch threaded pipe systems in commercial mechanical rooms, residential plumbing, hydronic heating, and light industrial fluid handling. The full-port design minimizes flow restriction, making it appropriate where pressure drop must be kept low. The reinforced RPTFE seat seal material resists wear and maintains a reliable shutoff across repeated cycles. It fits into any application requiring a threaded, full-bore isolation valve at 1-1/2 inch nominal pipe size.

Key Features

• Full-port ball design minimizes flow restriction through 1-1/2 inch line
• 600 PSI cold working pressure rating for demanding service environments
• Female NPT threaded ends on both sides for direct pipe thread connection
• Stainless steel ball and silicon bronze stem for corrosion resistance
• Reinforced RPTFE seat seal for extended cycle life and reliable shutoff
• NIBSEAL extended insulated handle for quarter-turn operation

Compatibility

Designed as an OEM-style replacement or new-installation isolation valve for 1-1/2 inch female NPT threaded piping systems in commercial, residential, mechanical, and industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off system pressure and drain the line before removing or installing any valve. Apply thread sealant or PTFE tape to male pipe threads before making up the connection — do not over-tighten threaded joints. Confirm valve orientation and handle clearance before final torque to allow full quarter-turn operation.
