American Valve 4001 4in 316SS Flanged Full Port Ball Valve 4in

Product Description

The AMERICAN VALVE 4001 4in is a 4-inch, full port ball valve constructed entirely from 316 stainless steel, including the body, ball, and stem. It is designed for flanged installation in commercial and industrial piping systems where corrosion resistance and full, unrestricted flow are required. The flanged end connections allow direct bolt-up to standard pipe flanges without additional fittings. Certified to NSF/ANSI 61 and NSF/ANSI 372 for contact with potable water, and rated to API 607 for fire-safe performance, this valve suits demanding service environments. A lever handle is included for manual quarter-turn operation. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.

This valve is suited for 4-inch flanged piping systems in water treatment, municipal water distribution, commercial plumbing, HVAC hydronic systems, and industrial process lines where stainless steel construction is specified. The full port design delivers unrestricted flow with minimal pressure drop, making it appropriate for applications where flow efficiency is critical. NSF/ANSI 61 and 372 certification qualifies it for use in potable water systems where lead content and material safety compliance are required by code.

Key Features

• Full port design minimizes flow restriction and pressure drop through the valve
• 316 stainless steel construction throughout for superior corrosion resistance
• Flanged end connections for direct bolt-up to standard pipe flanges
• NSF/ANSI 61 and NSF/ANSI 372 certified for potable water applications
• API 607 rated for fire-safe service
• Lever handle included for quick quarter-turn manual operation

Compatibility

Designed for use in 4-inch flanged piping systems requiring a full port stainless steel ball valve. Suitable for potable water, HVAC hydronic, and industrial process applications where NSF/ANSI 61, NSF/ANSI 372, and API 607 compliance is required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. Isolate and depressurize the system completely before removing any existing valve or making flanged connections. Align flanges carefully and torque bolts evenly in a cross pattern to ensure a leak-free seal without distorting the valve body. Verify flow direction and handle clearance before returning the system to service.
