Pulsafeeder J61020 KTC1/KTCJ Injection Check Valve - 3/8-Inch OD
3/8-Inch OD x 1/2-Inch NPT Chemical Injection Valve
Injection back-check valve with PVDF body, PTFE seat, ceramic check ball, 3/8-inch OD discharge tubing and 1/2-inch male NPT process fitting for KTC1 and KTCJ wet ends.
Correct Injection Valve Selection for KTC1 and KTCJ Pumps
The Pulsafeeder J61020 is designed for chemical metering pumps with KTC1 and KTCJ wet ends. Its 3/8-inch OD tubing connection and PVDF/PTFE/ceramic construction distinguish it from larger injection valve assemblies.

Why Tubing Size Is Important
J61020 is intended for 3/8-inch outside-diameter discharge tubing. J61021 uses 1/2-inch OD tubing. Selecting the correct valve prevents a mismatch between the pump discharge line and injection assembly.
How the Check Valve Works
During pump discharge, liquid passes through the check mechanism into the process connection. The valve helps resist reverse movement of process fluid when discharge conditions change.
PVDF Body and Ceramic Ball
The PVDF housing and ceramic check ball match the original KTC-series valve configuration. The PTFE seat is another important material specification. Confirm compatibility with the chemical being metered.
Replacement Checklist
- Confirm the KTC1 or KTCJ wet-end code.
- Measure the outside diameter of the discharge tubing.
- Check the 1/2-inch male NPT injection connection.
- Inspect the original valve for deposits and leakage.
- Follow the manufacturer service procedure.
