American Valve 4000 4in Cast Iron Flanged Full Port Ball Valve

Product Description

The AMERICAN VALVE 4000 4in is a full port, flanged ball valve constructed from cast iron, designed for isolation and flow control in commercial and industrial piping systems. Rated at 200 WOG (Water, Oil, Gas) and certified to NSF/ANSI 61 and NSF/ANSI 372, this valve meets potable water contact requirements and low-lead compliance standards. At 77 pounds, it is built for heavy-duty service. The included handle allows for quarter-turn manual operation. Licensed plumbers and pipefitters are the primary installers of valves at this size and pressure class.

This valve is suited for 4-inch flanged piping installations in commercial plumbing, waterworks, industrial process, and mechanical room applications. The full port design minimizes pressure drop across the valve, making it appropriate for systems where flow restriction is a concern. The flanged end connections allow for bolted installation between standard pipe flanges, which is common in larger-diameter commercial and municipal water systems.

Compatibility

Designed as an OEM-style replacement or new installation ball valve for 4-inch flanged piping systems rated to 200 WOG in commercial plumbing and industrial applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. Shut off and depressurize the system completely before removing any existing valve or making flange connections. Verify flange bolt pattern and gasket compatibility with existing piping before installation. Due to the 77-pound weight of this valve, mechanical lifting assistance is recommended during positioning and bolting.
