Backflow Protection at the Injection Point

The valve provides a one-way check function where the chemical discharge line connects to the process system. It helps prevent process liquid from flowing backward toward the metering pump.

PVC Housing and Viton Seat

Part 41695 uses PVC construction with Viton sealing and a ceramic check ball. This differs from part 41696, which uses a polypropylene body with the same nominal tubing size and sealing material designation.

Connection Selection

Confirm the 3/8-inch tubing connection and the original process-side fitting before replacement. The published short description does not establish every process-side connection dimension.

Chemical Compatibility

Check the suitability of PVC, Viton and ceramic for the specific chemical being metered. Material compatibility depends on concentration, temperature and operating conditions.

Maintenance

Inspect the check valve for chemical deposits, leakage and worn seating surfaces. Isolate and depressurize the system before removal.
