Injection Point Backflow Protection
The injection check valve connects the metering pump discharge tubing to the process line. Its internal check mechanism permits chemical solution to enter the process while helping resist reverse flow of process liquid into the feed line.
PVC Housing and Viton Seat
The PVC body and Viton sealing configuration distinguish J41867 from valves using FPP housings or PTFE and CSPE seats. Correct material selection is important for reliable operation in chemical metering applications.
316 Stainless Steel Check Ball
The stainless steel ball is an important replacement specification. It should not be substituted with ceramic or PTFE without verifying the original liquid-end design and chemical compatibility.
VVS1 Wet-End Compatibility
Distributor listings identify J41867 for PULSAtron VVS1 wet ends. Confirm the original pump model, 3/8-inch OD tubing and 1/2-inch male NPT process connection before ordering.
Installation and Maintenance
Inspect the injection fitting for deposits, leakage and damaged threads. Check the valve seat and ball for contamination when investigating restricted chemical flow. Isolate and depressurize the system before service.
