Nibco MD910A6 True Union Ball Valve 1/2 in Full Port Pvdf

Product Description

The NIBCO MD910A6 is a true union design ball valve built for demanding fluid handling applications where chemical resistance and reliable shutoff are required. Constructed from polyvinylidene fluoride (PVDF), this 1/2-inch full-port valve handles working pressures up to 150 psi and temperatures up to 280 degrees F. The true union body style allows the valve to be removed from the line without disturbing adjacent piping, making maintenance and replacement significantly faster. A wedge-style handle provides positive on/off control. Rated for Schedule 80 service, it is suited for chemical processing, industrial piping, and corrosive-fluid systems where metal valves are not appropriate. Licensed plumbers and industrial pipefitters are the typical installers.

This valve is designed for use in systems conveying corrosive or high-purity fluids where PVDF material compatibility is a primary selection factor. The 1/2-inch pipe size and FNPT x FNPT end connections allow direct threaded installation into existing Schedule 80 PVC or CPVC lines or independent PVDF piping systems. Full-port construction minimizes flow restriction, which is important in dosing, chemical feed, and water treatment applications. The true union design is especially useful in confined mechanical spaces where periodic valve service is expected.

Key Features

• PVDF body construction resists a broad range of corrosive and aggressive chemicals
• Full-port ball design maintains maximum flow capacity with minimal pressure drop
• True union configuration allows in-line removal without cutting or disturbing adjacent pipe
• Rated to 150 psi maximum working pressure
• Handles fluid temperatures up to 280 degrees F
• FNPT x FNPT end connections for direct threaded installation
• Wedge handle provides clear visual open/closed indication

Compatibility

Designed as an OEM-style replacement or new-installation valve for 1/2-inch Schedule 80 threaded piping systems requiring PVDF chemical resistance and full-port flow characteristics.

Installation Notes

Installation is typically performed by a licensed plumber or industrial pipefitter familiar with thermoplastic piping systems. Depressurize and drain the line fully before removing any existing valve or fitting. Apply appropriate thread sealant compatible with PVDF and the conveyed fluid — verify sealant chemical compatibility before use. Follow applicable IPC and local code requirements for plastic piping in chemical service environments.
