Chemical Injection Function

The valve provides a one-way flow path at the process injection point. Its internal check mechanism helps resist reverse flow of process liquid into the metering pump discharge tubing.

Viton Seat and PTFE Ball

The Viton seat and PTFE check ball distinguish J41775 from ceramic-ball or Hypalon-seated injection valve alternatives. Match the original liquid-end material configuration.

1/2-Inch OD Tubing Configuration

J41775 is listed for 3/8-inch inside-diameter by 1/2-inch outside-diameter tubing. The related J41774 uses smaller 1/4-inch ID by 3/8-inch OD tubing.

Material Compatibility

Verify the suitability of FPP, Viton and PTFE for the actual chemical concentration and operating temperature. Do not assume universal compatibility.

Installation and Inspection

Confirm the original pump model, tubing and process fitting. Inspect the valve for chemical deposits, damaged connections and leakage before returning the system to service.
