Krowne 21-470 NLA-1-25-24 Ceramic Cartridge Valve

Product Description

The KROWNE 21-470 NLA-1-25-24 is a cold ceramic cartridge valve designed for use in commercial plumbing and foodservice equipment applications. Ceramic cartridge valves provide precise flow control and long service life by using tight-tolerance ceramic discs that resist wear and mineral buildup better than traditional rubber-seat valves. This valve handles the cold water supply side and is typically installed by licensed plumbers or qualified service technicians during equipment repair or replacement service.

This cold ceramic cartridge valve is suited for commercial sink faucets, bar equipment, and foodservice plumbing fixtures where reliable cold water shutoff and flow control are required. It is commonly installed as a direct replacement cartridge during routine maintenance or when the original valve shows signs of leaking or restricted flow. Always verify handle orientation and cartridge seat dimensions before installation.

Key Features

• Designed for cold water supply lines in commercial plumbing applications
• Drop-in cartridge format simplifies replacement without full valve body removal

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the cold water supply and relieve line pressure before removing the existing cartridge. Inspect the valve seat and body for damage or scale buildup prior to inserting the new cartridge. Work performed on commercial foodservice equipment may be subject to local plumbing code requirements under the IPC or applicable state code.
