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

The Pulsafeeder L3300H03-PVC is a 1/2-inch PVC/CSPE bleed valve assembly for compatible PULSAtron chemical metering pump wet ends. It uses a PVC body with CSPE, also known as Hypalon, sealing material.

Controlled Air Bleeding

Air trapped in a diaphragm metering pump can interfere with priming. A bleed valve provides a means of venting air during the recommended startup or maintenance procedure, helping the operator establish liquid flow through the pump.

PVC/CSPE Material Combination

The H-series sealing configuration uses CSPE rather than PTFE. Material selection should match the original pump specification and be verified against the chemical solution being metered.

Choosing the Correct Size

The L3300H03-PVC is the 1/2-inch configuration. For equipment using 3/8-inch tubing, a different bleed valve part number may be required. Confirm the existing connection before purchase.

Typical Maintenance Situations

Bleed-valve inspection may be appropriate following leakage, damage to the adjustment mechanism or difficulty venting trapped air. Examine the surrounding fittings and tubing before replacement.

Installation Guidance

Follow the manufacturer instructions for valve orientation, return tubing and priming. Isolate the chemical system and release pressure before disassembly.
