Pulsafeeder L3300H03-FPP FPP/Hypalon Bleed Valve Assembly - 1/2-Inch OD

The Pulsafeeder L3300H03-FPP combines an FPP polypropylene body with CSPE/Hypalon sealing in a 1/2-inch bleed valve assembly. It is designed for compatible PULSAtron chemical metering pump liquid ends.

Priming and Venting Function

During startup or after maintenance, a metering pump may contain trapped air. The bleed valve provides a controlled venting point to assist priming when operated according to the pump manual.

FPP Body and Hypalon Sealing

This valve differs from L3300H03-PVC in body material. It also differs from the T-series FPP valves, which use PTFE seals. Match both body and sealing materials to the original equipment specification.

Suitable Replacement Applications

Use the assembly when the existing PULSAtron wet end specifies an FPP/CSPE 1/2-inch bleed valve. Verify the full pump model before ordering, especially when replacing a valve from an older installation.

Maintaining the Bleed Connection

Inspect the fitting and adjustment components for deposits, damage and chemical leakage. Check the return tubing and sealing surfaces during maintenance.

Safe Installation

Isolate power, depressurize the liquid end and follow the manufacturer instructions. Confirm the valve connection and material configuration before restarting the pump.
