One-Way Chemical Injection

Installed at the chemical discharge connection, the valve permits metered solution to enter the process system while helping resist reverse flow toward the pump. This check-valve function is important for maintaining the intended direction of chemical delivery.

Polypropylene Housing

The polypropylene body distinguishes part 41659 from PVC-bodied injection valves such as 41661. Housing material is an important selection criterion for chemical feed equipment and should match the original pump configuration.

Viton Seat and Ceramic Ball

The Viton seat and ceramic ball form the specified internal check mechanism. Chemical compatibility must be verified for the actual process fluid, concentration and operating temperature.

Connection and Replacement Selection

The manufacturer catalog identifies a 1/2-inch tubing connection. Confirm the original valve, discharge tubing dimensions and mating process fitting before installation. Do not assume an unspecified process-side thread size.

Inspection and Maintenance

Inspect the valve for chemical deposits, worn seating surfaces, damaged fittings and leakage. Isolate and depressurize the chemical feed system before servicing.
