Pulsafeeder L3201TC3-FPP Discharge Valve Assembly
The Pulsafeeder L3201TC3-FPP is a genuine Pulsatron discharge valve assembly for pumps with the PTC3 wet end: a GFPPL body with PTFE seat and O-ring and ceramic check ball, and a 1/2 in OD tubing connection. It threads into the top of the pump head, where it opens on the discharge stroke to send chemical out to the injection point and closes on the suction stroke so the discharge line cannot drain back into the head.
A check valve that is not seating cleanly is the most common reason a solenoid metering pump loses output or will not hold prime. Crystals from the chemical, grit past a damaged strainer, or a swollen O-ring are the usual causes, and the fix is a new cartridge rather than cleaning an old one. The PTC3 code is the second half of the pump model number, so check the label before ordering. The same cartridge is part of the size 4 through 7 PTC3 KOPkits.

Frequently Asked Questions
Q: How tight should it be?
Hand tight plus a small amount with a wrench. The O-ring does the sealing, and overtightening a plastic body can crack it or distort the seat.
Q: Should I replace both valves at once?
It is good practice. Suction and discharge valves see the same chemical and the same number of cycles, so they usually wear together.
Q: Can I just clean the old valve?
Flushing with water can free a valve stuck by crystals for a while, but a worn seat or swollen O-ring will not recover. A new cartridge restores full output.
Q: Why is my pump still losing prime with new valves?
Look for an air leak at the suction tubing connection, a blocked foot valve strainer, or gas building in the head. Bleeding the head after startup clears trapped air.
