Pulsafeeder J30519 FPP/CSPE Hypalon Bleed Valve Kit - 1/2-Inch

Pulsafeeder J30519 FPP/CSPE Hypalon Bleed Valve Kit

The Pulsafeeder J30519 is a 1/2-inch FPP/CSPE bleed valve kit for compatible CHEM-TECH chemical metering pumps. The manufacturer parts schedule identifies its sealing material as CSPE, also commonly referred to as Hypalon.

Hypalon-Sealed Bleed Valve Configuration

J30519 is distinguished by its FPP body and CSPE/Hypalon sealing designation. This material configuration should be matched to the original liquid end rather than substituted solely on the basis of connection size.

Supporting Pump Priming

During startup or maintenance, trapped gas may prevent a chemical metering pump from establishing normal liquid delivery. The bleed valve provides a controlled route for releasing air when operated according to the manufacturer procedure.

Difference from Other Bleed Valve Kits

J30519 uses FPP/CSPE materials with a 1/2-inch tubing connection. J30522 uses FPP/PTFE with the same nominal tubing size, while J30511 is the smaller 3/8-inch FPP/CSPE configuration.

Chemical Compatibility Considerations

CSPE is used in selected chemical-handling components, but suitability depends on the actual chemical, concentration and temperature. Confirm the original housing and seal requirements before installing a replacement.

Maintenance and Inspection

Inspect the bleed connection for leaks, deposits and damaged fittings. Follow the manufacturer service instructions and relieve pressure before replacing the valve kit.
