Injection Check-Valve Function

The valve is installed at the chemical injection connection and provides a one-way check mechanism. It helps prevent process liquid from flowing backward toward the metering pump discharge line.

VHC4 Wet-End Compatibility

The manufacturer parts guide identifies J41904 as the injection valve for the VHC4 wet-end configuration. Matching the original wet-end code is important because similar valves may have different seats, balls or connection arrangements.

PVC, Hypalon and Ceramic Construction

The PVC housing, CSPE/Hypalon seat and ceramic check ball are defining specifications of this part. Verify the compatibility of all wetted components with the chemical being injected.

Connection Verification

The published part listing specifies a 1/4-inch NPT connection. Confirm the mating fitting and complete original installation before purchasing, rather than assuming a tubing outside diameter.

Maintenance and Inspection

Inspect the injection valve for leakage, chemical deposits, damaged threads and contamination around the ball and seat. Relieve system pressure before removal.
