Chemical Injection Backflow Protection

The valve is installed at the chemical injection point where the metering pump discharge line connects to the process system. Its internal check mechanism helps resist reverse flow of process liquid toward the metering pump.

FPP Housing and PTFE Seat

The FPP housing and PTFE seat distinguish J41944 from injection valves using PVC bodies, Viton seats or Hypalon seals. The ceramic check ball forms part of the specified one-way valve assembly.

PTC2 and PTC4 Compatibility

Distributor listings identify this part for PTC2 and PTC4 wet ends. Verify the complete pump model and original injection valve part number before selecting a replacement.

NPT Connection Requirements

The inlet is specified as 1/4-inch female NPT, with a 1/2-inch male NPT process connection. These threaded connections should not be confused with outside-diameter tubing fittings.

Installation and Maintenance

Inspect the check valve for chemical deposits, leakage, damaged threads and check-ball contamination. Relieve system pressure before removing the injection assembly.
