Nibco MD909AA True Union Ball Valve 1 in Full Port Pvdf

Product Description

The NIBCO MD909AA is a true union manual ball valve designed for full-port flow control in demanding chemical and industrial fluid handling systems. Built from polyvinylidene fluoride (PVDF), this valve withstands corrosive media that would degrade standard thermoplastic valves. The one-piece body construction with true union end connections allows the valve to be removed from the line without cutting pipe. Rated to 150 psi and 280 degrees F, it suits high-temperature and chemically aggressive service environments. A wedge-style handle provides positive open and closed indication. Schedule 80 construction adds wall thickness for additional pressure integrity.

This valve is suited for residential and commercial plumbing, chemical processing, water treatment, and industrial piping systems where corrosion resistance is a priority. The solvent x solvent end connections make it compatible with Schedule 80 CPVC and PVDF piping systems. It is commonly installed by licensed plumbers and pipefitters in applications involving acids, bases, or other aggressive fluids that require non-metallic valve bodies. The full-port design minimizes pressure drop across the valve, which is important in flow-critical installations.

Key Features

• PVDF body material offers superior resistance to corrosive chemicals and high temperatures
• Full-port design minimizes flow restriction and pressure drop
• True union construction allows in-line removal without cutting pipe
• Rated to 150 psi maximum working pressure
• Rated to 280 degrees F maximum working temperature
• Schedule 80 wall thickness for added pressure integrity
• Wedge handle provides clear open and closed indication

Compatibility

Designed as an OEM-style replacement or new-installation valve for Schedule 80 PVDF and compatible thermoplastic piping systems using solvent cement end connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic solvent-welding procedures. Depressurize and drain the line completely before removing or installing the valve. Follow solvent cement manufacturer cure times before returning the line to service. Consult applicable plumbing codes, including the IPC, for pressure testing requirements after installation.
