Injection Point Backflow Protection

The injection valve is fitted at the end of the chemical discharge tubing where the metering pump connects to the process line. Its internal check mechanism allows chemical delivery toward the process while helping resist reverse flow of process liquid into the feed line.

PVC Housing and PTFE Seat

The PVC and PTFE materials distinguish J41873 from Viton-seated injection valves. The ceramic check ball forms part of the one-way flow mechanism. Material compatibility must be checked against the chemical concentration and operating temperature.

Connection and Wet-End Compatibility

Verify the 1/2-inch OD tubing, 1/2-inch male NPT process connection and original VTC3, VTCA or WTC3 wet-end designation. Similar injection valves can use different connection sizes or sealing materials.

Installation and Maintenance

Inspect the injection point for deposits, leaks and damaged threads. Check the check-ball and seat area for contamination. Isolate the chemical feed system and relieve pressure before replacing the valve.
