Nibco MA0013H Miniature Ball Valve 4 in Standard Port

Product Description

The NIBCO MA0013H is a miniature manual ball valve designed for 4-inch pipe applications requiring a compact, reliable shutoff solution. Constructed from polyvinylchloride (PVC), this valve is suited for low-pressure fluid handling systems where corrosion resistance and chemical compatibility are priorities. It features a standard port configuration with female NPT connections on both ends and a tee-style handle for straightforward manual operation. Schedule 40 compatibility makes it a practical fit for standard PVC piping systems. Licensed plumbers and mechanical contractors are the typical installers for this type of valve in commercial and industrial piping runs.

This valve is intended for use in residential and commercial plumbing, irrigation, and industrial fluid-handling systems that utilize Schedule 40 PVC pipe at 4-inch diameter. The FNPT x FNPT end connections allow direct threaded installation into existing pipe configurations without adapters. The natural PVC color finish indicates standard, unrated PVC construction. It is well suited for water treatment, chemical distribution, and irrigation control applications where metal valves would be subject to corrosion.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes and the IPC. Depressurize and drain the pipe system completely before removing or installing any valve. Use appropriate thread sealant compatible with PVC and the media being handled — avoid over-tightening threaded connections on PVC fittings, as excess torque can crack the body. Verify system pressure and temperature ratings are within the valve's listed service range before returning the system to service.
