One-Way Chemical Injection

The valve provides a one-way flow path from the chemical metering pump discharge line into the process system. Its check mechanism helps resist reverse flow toward the chemical feed equipment.

Viton Seat and Ceramic Ball

The Viton seat and ceramic ball distinguish J41901 from the PTFE-seated J41944 and Hypalon-seated J41911 injection valves. The correct seat material must match the original equipment and chemical application.

FPP Housing

The FPP body is a polypropylene-family construction used in selected chemical metering pump liquid ends. Verify its suitability for the process chemical and temperature before installation.

Threaded Connection

The valve is listed with a 1/4-inch female NPT inlet and 1/2-inch male NPT process connection. Confirm the mating fittings and original pump arrangement before ordering.

Maintenance and Inspection

Inspect the valve for deposits, leakage, damaged threads and check-ball contamination. Follow the manufacturer service instructions and depressurize the system before removal.
