One-Way Chemical Injection
The valve helps prevent reverse flow from the process system into the chemical feed line while permitting metered solution to enter the injection point.
316 Stainless Steel Check Ball
The 316 stainless steel ball distinguishes J41881 from ceramic-ball and PTFE-ball injection valve alternatives. Stainless steel chemical compatibility must be evaluated for the actual process conditions.
VTS3 and WTS3 Compatibility
Distributor listings identify the valve for VTS3 and WTS3 wet ends. Confirm the 1/2-inch OD tubing and original wet-end designation before replacement.
Maintenance and Inspection
Inspect for deposits, damaged threads, leakage and check-valve contamination. Relieve system pressure before removing the assembly.
