Pulsafeeder J41669 PVC Double-Ball Discharge Check Valve Cartridge - 1/2-Inch

Pulsafeeder J41669 PVC Double-Ball Discharge Check Valve Cartridge

The Pulsafeeder J41669 is a 1/2-inch PVC double-ball discharge check valve cartridge listed in CHEM-TECH Series 250 mechanical diaphragm metering pump parts schedules. It is intended for the discharge-side valve position of compatible liquid-end assemblies.

Discharge-Side Chemical Flow Control

During the discharge stroke, the pump diaphragm moves chemical solution from the liquid end toward the discharge line. The discharge check valve supports this intended flow direction while helping resist liquid movement back into the pump head.

Double-Ball Cartridge Construction

The double-ball arrangement provides check-valve action within the cartridge. Proper movement and seating of the internal components are important for the pump to complete its intended chemical metering cycle.

Difference Between J41669 and J41667

J41669 and J41667 are both listed as 1/2-inch PVC double-ball cartridges, but they are assigned to different valve positions. J41669 is the discharge cartridge, while J41667 is the suction cartridge.

Inspection and Maintenance

Inspect the cartridge for chemical deposits, contamination and damaged seating surfaces. A discharge valve that does not seat correctly may contribute to reverse leakage or irregular metering performance.

Installation Considerations

Confirm the original liquid-end arrangement and cartridge orientation. Depressurize the discharge system and follow the manufacturer service instructions before removing valve components.
