Mazzei (SPSA-1.5-A) Suction Port Screen w- Check Valve - 1.5" FNPT Connection
Mazzei SPSA-1.5-A Suction Port Screen Assembly with Check Valve
The Mazzei SPSA-1.5-A is a dual-function component that screens particulate from chemical feed lines while preventing reverse flow when the injector shuts down. This assembly threads directly onto the suction port of compatible 1.5-inch Mazzei injectors, eliminating the need for separate screen and check valve installations.
