Pulsafeeder J41667 PVC Double-Ball Suction Check Valve Cartridge - 1/2-Inch

Pulsafeeder J41667 PVC Double-Ball Suction Check Valve Cartridge

The Pulsafeeder J41667 is a 1/2-inch PVC double-ball suction check valve cartridge assembly identified in CHEM-TECH Series 250 metering pump parts schedules. Unlike discharge-side cartridges, this component is specified for the suction inlet of the pump liquid end.

Function During the Pump Suction Stroke

As the metering pump diaphragm moves through its suction stroke, chemical solution is drawn into the liquid end through the inlet valve. The suction check valve permits the intended inlet flow and helps resist reverse movement toward the chemical supply during the discharge stroke.

Supporting Chemical Intake

Proper suction check-valve operation is important for drawing chemical solution from the supply tank into the metering pump. Contamination, worn components or damaged seating surfaces may interfere with normal valve action.

Suction Cartridge Versus Discharge Cartridge

J41667 is the suction-side cartridge. J41669 is a separate 1/2-inch discharge cartridge. Matching the valve position is as important as confirming the connection size and pump model.

Troubleshooting Suction Problems

When a chemical metering pump has difficulty drawing solution, inspect the suction tubing, foot valve, inlet strainer and suction check cartridge. Check for restrictions, air leaks, deposits and damaged valve components.

Maintenance and Replacement

Disconnect power, isolate the chemical supply and relieve system pressure before disassembly. Follow the CHEM-TECH service manual to confirm cartridge orientation and installation requirements.
