Pulsafeeder J41872 FPP/PTFE/Ceramic Injection Valve - PTC3/PTCA
FPP/PTFE/ceramic injection check valve with 1/2-inch OD tubing and 1/2-inch male NPT connection. Designed for compatible PULSAtron PTC3 and PTCA wet ends.
FPP/PTFE/Ceramic Injection Valve for PTC3 and PTCA Pumps
The Pulsafeeder J41872 is an injection back-check valve assembly for selected PULSAtron PTC3 and PTCA wet ends. It uses a ceramic check ball together with an FPP housing and PTFE seat, distinguishing it from PTFE-ball injection valve configurations.

The Role of the Ceramic Check Ball
The ceramic ball forms part of the one-way check mechanism. As discharge pressure opens the valve, metered liquid can move into the process; the valve is intended to resist reverse movement when flow conditions change. Material selection should follow the original manufacturer configuration.
PTC3 and PTCA Liquid-End Selection
Pulsafeeder replacement-parts documentation identifies J41872 as an injection valve for PTCA wet ends, while distributor listings also identify PTC3. Match the complete pump model and liquid-end code before installation.
Where the Valve Is Installed
The assembly connects to the discharge tubing at the chemical injection point. The 1/2-inch OD tubing fitting and 1/2-inch male NPT process connection must match the installation.
Inspection During Routine Service
Check for damaged fittings, chemical deposits, leaking connections and check-valve contamination. Use the correct replacement part rather than substituting a valve with different seat or ball materials.
Product Selection
Specify Pulsafeeder J41872 for the FPP/PTFE/ceramic injection check valve used with compatible PTC3 and PTCA configurations.
