Chemical Injection Application

The valve is installed at the discharge-side injection point. Its internal check mechanism allows chemical solution to enter the process system while helping prevent reverse flow toward the metering pump.

PVC Housing and Viton Seat

The PVC body and Viton seat distinguish J41761 from FPP/CSPE injection valves. The PTFE check ball is another important material specification and should match the original VVT3 liquid-end configuration.

VVT3 Wet-End Compatibility

Distributor listings identify J41761 for VVT3 wet ends with 1/2-inch OD discharge tubing. Confirm the complete pump model and connection dimensions before selecting the replacement.

Connection and Chemical Compatibility

The 1/2-inch male NPT injection fitting must match the process connection. Verify PVC, Viton and PTFE compatibility with the actual chemical concentration and operating temperature.

Inspection and Maintenance

Inspect the valve for deposits, leakage, damaged threads and contamination of the seat and ball. Isolate and depressurize the system before servicing.
