Injection Point Backflow Protection
The valve provides a one-way flow path from the chemical metering pump discharge tubing into the process system. Its internal check mechanism helps resist reverse flow into the chemical feed line.
CSPE Seat and Stainless Steel Ball
The CSPE/Hypalon seat and 316 stainless steel ball distinguish J41865 from PTFE-ball or ceramic-ball injection valves. Material selection must match the original pump configuration and process chemical.
Connection Requirements
Confirm the 1/2-inch OD discharge tubing and 1/2-inch male NPT process fitting. Similar injection valves can use different tubing dimensions despite having comparable housing designs.
Chemical Compatibility
Verify the suitability of PVC, CSPE and 316 stainless steel for the actual chemical service. Stainless steel is not compatible with every corrosive chemical.
Inspection and Maintenance
Inspect for deposits, leaks, damaged threads and check-ball contamination. Isolate and depressurize the process system before maintenance.
