Backflow Protection

The valve is installed at the injection point where the metering pump discharge line meets the process system. Its one-way check mechanism helps prevent reverse movement of process liquid.

FPP Housing

The glass-filled polypropylene housing identifies the material configuration used in this assembly. It should match the original equipment and intended chemical application.

Viton and PTFE Components

The Viton seat and PTFE ball are important replacement specifications. These components distinguish J41774 from Hypalon-seated and ceramic-ball injection valve assemblies.

3/8-Inch OD Tubing

The listed connection uses 1/4-inch inside-diameter by 3/8-inch outside-diameter tubing. Verify the complete pump model and mating process fitting before installation.

Inspection and Maintenance

Check for chemical buildup, leakage, damaged threads and contamination of the check components. Isolate and depressurize the system before removing the valve.
