Backflow Protection at the Injection Point
The valve is installed where the chemical discharge line connects to the process system. Its internal check mechanism helps prevent reverse movement of process liquid toward the metering pump.

Manufacturer parts schedules list a 3/8-inch tubing designation for 41657. Confirm the original tubing dimensions and process-side connection before replacement.
CHEM-TECH Pump Applications
This part appears in CHEM-TECH replacement-parts schedules. Exact compatibility should be confirmed using the original pump model, parts diagram and liquid-end configuration.
Chemical Compatibility
Verify PVC, Hypalon and ceramic compatibility with the process chemical, concentration and operating temperature. Different CHEM-TECH valve assemblies use different material combinations.
