Pulsafeeder J30517 PVC/Viton Bleed Valve Kit - 1/2-Inch

Pulsafeeder J30517 PVC/Viton Bleed Valve Kit

The Pulsafeeder J30517 is a PVC/Viton bleed valve kit with a 1/2-inch tubing connection, documented in CHEM-TECH chemical metering pump replacement-parts listings. Its Viton/FKM sealing designation distinguishes it from otherwise similar PTFE-sealed bleed valve configurations.

Viton-Sealed Chemical Pump Bleed Valve

The bleed valve is part of the pump priming arrangement. When operated according to the manufacturer instructions, it provides a path for releasing trapped air that may interfere with normal liquid delivery.

Difference Between Viton and PTFE Kits

J30517 is the PVC/Viton version, whereas J30518 is the PVC/PTFE version. Both have a nominal 1/2-inch tubing designation. Material compatibility and the original equipment configuration determine which replacement should be selected.

Chemical Compatibility Considerations

Viton is a fluoroelastomer used in selected chemical-handling components. Its resistance varies with the chemical, concentration and temperature. Confirm the suitability of the complete PVC/Viton wetted assembly before installation.

Priming and Troubleshooting

Trapped gas, blocked suction tubing and damaged check valves can all affect metering pump operation. Inspect the bleed valve as part of a complete troubleshooting procedure rather than assuming it is the only possible cause of priming problems.

Service Recommendations

Check for leaks, chemical deposits, damaged connections and worn sealing surfaces. Depressurize the pump and follow the applicable CHEM-TECH maintenance procedure before replacing components.
