One-Way Chemical Injection

The valve connects the metering pump discharge line to the process injection point. Its internal check mechanism helps prevent reverse movement of process liquid toward the pump tubing and chemical supply.

Viton Seat and Ceramic Ball

The Viton seat and ceramic check ball are defining specifications of J61237. These materials distinguish it from PTFE-seated injection valves, including J41873. Confirm compatibility with the chemical being injected.

Correct Connection Selection

J61237 uses 3/8-inch OD tubing and a 1/2-inch male NPT process connection. Confirm the tubing outside diameter and original wet-end code before selecting the replacement.

Inspection and Troubleshooting

Check for chemical buildup, damaged fittings, leakage and check-valve contamination when investigating restricted discharge flow or injection-point problems.

Installation Precautions

Isolate the process line, relieve system pressure and follow the manufacturer installation instructions. Confirm the tubing coupling is secured correctly before returning the pump to service.
