VTT1 Injection Application
The valve connects the metering pump discharge tubing to the chemical injection point. Its internal check mechanism helps resist reverse movement of process liquid toward the pump.
PTFE Seat and Check Ball
J41876 uses PTFE for both the seat and check ball. This distinguishes it from injection valves fitted with ceramic or stainless steel check balls. Confirm that the original liquid-end configuration requires these materials.
3/8-Inch Tubing Connection
The valve is listed with a 3/8-inch OD tubing connection and a 1/2-inch male NPT process fitting. Match both connections and verify the complete VTT1 pump model before replacement.
Installation and Maintenance
Attach the discharge tubing according to the manufacturer instructions. Inspect the valve for deposits, leakage, damaged threads and contamination of the seat or check ball. Relieve system pressure before servicing.
