VHT3 Chemical Injection Application
Installed at the end of the pump discharge tubing, J41759 connects the chemical feed line to the injection point. Its check mechanism helps prevent reverse flow from the process system and supports the intended discharge arrangement.
CSPE Seat and PTFE Check Ball
The CSPE/PTFE material combination distinguishes J41759 from ceramic-ball injection valves. Verify the original wet-end code and chemical compatibility rather than selecting solely by connection size.
1/2-Inch Tubing Connection
The 1/2-inch OD tubing connection is a key difference from J41758, which uses 3/8-inch OD tubing. Both have a 1/2-inch male NPT injection connection but are listed for different wet ends.
Maintenance and Inspection
Check the injection fitting for deposits, leakage and damaged threads. Inspect the check-valve components for contamination when troubleshooting restricted chemical delivery.
